Input variables for eos_designs

This document describes the supported input variables for the role arista.avd.eos_designs.

Since several data models have changed between AVD versions 4.x and 5.x, it is recommended to study the Porting Guide for AVD 5.x.x for existing deployments.

The input variables are documented below in tables and YAML.

Note

All input variables are validated by a schema. If additional custom keys are desired, a key starting with an underscore _, will be ignored.

Warning

Available features and variables may vary by platforms, refer to documentation on arista.com for specifics.

Warning

All the keys marked as PREVIEW or children of a key marked as PREVIEW are subject to change and are not supported.

Supported designs

eos_designs supports multiple options such as L3LS-EVPN with 3-stage or 5-stage, L2LS, MPLS, AutoVPN and CV Pathfinder. The sections below highlight some of these topologies, but you can extend eos_designs to support your own topology by using node_type_keys to create your own node type.

Design type

Note

The design.type variable is no longer required. It has been deprecated and will be removed in AVD 6.0.0. The default Node Type Variables can be used with all designs.

Variable Type Required Default Value Restrictions Description
design deprecated Dictionary This key is deprecated. Support will be removed in AVD version 6.0.0. See here for details.
  type String l3ls-evpn Valid Values:
- l3ls-evpn
- mpls
- l2ls
By setting the design.type variable, the default node-types and templates described in these documents will be used.
# This key is deprecated.
# Support will be removed in AVD version 6.0.0.
# See [here](https://avd.arista.com/stable/docs/release-notes/5.x.x.html#deprecation_of_design.type) for details.

  # By setting the design.type variable, the default node-types and templates described in these documents will be used.
  type: <str; "l3ls-evpn" | "mpls" | "l2ls"; default="l3ls-evpn">

3-stage clos topology support (Leaf & Spine)

  • The eos_designs role support various deployments with layer 3 leaf and spine (3-stage Clos) and optionally, with dedicated overlay controllers.
  • 3 stage Clos fabric can be represented as spines, L3 leafs and L2 leafs, and also referred to as a “POD”.

See the following examples:

5-stage clos topology support (Super Spine)

  • The eos_designs role support larger deployments with super-spines (5-stage Clos) and optionally, with dedicated overlay controllers.
  • 5 stage Clos fabric can be represented as multiple leaf-spine structures (called PODs - Point of Delivery) interconnected by super-spines.
  • The logic to deploy every leaf-spine POD fabric remains unchanged.
  • Super-spines can be deployed as a single plane (typically chassis switches) or multiple planes.

Layer 2 Leaf Spine

  • The eos_designs role support various deployments with layer 2 leaf and spine. For example, routing may terminate at the spine level or an external L3 device.
  • The Clos fabric can be represented as L3 spines, spines, and leafs.

See the following examples:

MPLS

The eos_designs role supports any arbitrary physical mesh topology by combining and interconnecting different node types with the core_interfaces settings.

The following underlay routing protocols are supported:

  • ISIS-SR (default)
  • ISIS + LDP
  • ISIS-SR + LDP
  • OSPF + LDP

The following overlay routing protocols are supported:

  • IBGP (default)

Any node group of 2 or more rr-routers will form a Route Reflector cluster.

The MPLS design supports most fabric topology variables already supported by l3ls-evpn, barring the exceptions outlined below:

  • Connectivity is defined with the core_interfaces settings instead of Node type uplink settings.
  • No MLAG support.
  • No VXLAN support.
  • EVPN overlay settings are set with mpls_overlay_role and mpls_route_reflectors instead of evpn_role and evpn_route_servers.
  • No Inband Management support.

See the following example:

WAN - AutoVPN and CV Pathfinder

The eos_designs role with the l3ls-evpn design type supports the node types wan_rr and wan_router. The default underlay routing protocol is set to none but eBGP is supported as well.

The following overlay routing protocols are supported:

  • IBGP (default)

For more information please read the WAN how-to guide.

Fabric topology hierarchy

5 stage topology

As per the diagram above, the topology hierarchy is the following:

  • fabric_name
    • dc_name
      • pod_name

You must define the fabric_name variable and it must match the Ansible inventory group name covering all devices in scope of the fabric.

Variable Type Required Default Value Restrictions Description
dc_name String DC Name is used in:
- Fabric Documentation (Optional, falls back to fabric_name)
- SNMP Location: snmp_settings.location (Optional)
- HER Overlay DC scoped flood lists: overlay_her_flood_list_scope: dc (Required)
fabric_name String Required Fabric Name, required to match Ansible Group name covering all devices in the Fabric, must be an inventory group name.
pod_name String POD Name is used in:
- Fabric Documentation (Optional, falls back to dc_name and then to fabric_name)
- SNMP Location: snmp_settings.location (Optional)
- VRF Loopbacks: vtep_diagnostic.loopback_ip_pools.pod (Required)

Recommended to be common between Spines and Leafs within a POD (One l3ls topology).
# DC Name is used in:
# - Fabric Documentation (Optional, falls back to fabric_name)

Fabric IP Addressing

Variable Type Required Default Value Restrictions Description
fabric_ip_addressing Dictionary
  mlag Dictionary
    algorithm String first_id Valid Values:
- first_id
- odd_id
- same_subnet
This variable defines the Multi-chassis Link Aggregation (MLAG) algorithm used.
Each MLAG link will have a /31* subnet with each subnet allocated from the relevant MLAG pool via a calculated offset.
The offset is calculated using one of the following algorithms:
- first_id: (mlag_primary_id - 1) * 2 where mlag_primary_id is the ID of the first node defined under the node_group.
This allocation method will skip every other /31* subnet making it less space efficient than odd_id.
- odd_id: (odd_id - 1) / 2. Requires the node_group to have a node with an odd ID and a node with an even ID.
- same_subnet: the offset will always be zero.
This allocation method will cause every MLAG link to be addressed with the same /31* subnet.
* - The prefix length is configurable with a default of /31.

Node type customization

AVD provides the capability to customize your node types, supporting a variety of designs.

Note

The default values will be overridden if this key is defined. If you need to change all the existing node_type_keys, it is recommended to copy the defaults and modify them. If you need to add custom node_type_keys, create them under custom_node_type_keys; if named identically to default node_type_keys entries, custom entries will replace the equivalent default entry.

The default value of node_type_keys depend on the design.type setting which is deprecated for removal in AVD 6.0.0. The default design type l3ls-evpn provides all the default node types mentioned in the previous section.

Context for ip_addressing templates

To help calculate the custom IP addressing, the following contextual variables are available to the custom templates:

router_id:

  • {{ switch_id }}
  • {{ loopback_ipv4_pool }}
  • {{ loopback_ipv4_offset }}
  • All group/hostvars

mlag_ip_primary & mlag_ip_secondary:

  • {{ mlag_primary_id }}
  • {{ mlag_secondary_id }}
  • {{ switch_data.combined.mlag_peer_address_family }}
  • {{ switch_data.combined.mlag_peer_ipv4_pool }}
  • {{ switch_data.combined.mlag_peer_ipv6_pool }}
  • All group/hostvars

mlag_l3_ip_primary & mlag_l3_ip_secondary:

  • {{ mlag_primary_id }}
  • {{ mlag_secondary_id }}
  • {{ switch_data.combined.mlag_peer_l3_ipv4_pool }}
  • All group/hostvars

p2p_uplinks_ip & p2p_uplinks_peer_ip:

  • All group/hostvars

vtep_ip:

  • {{ switch_vtep_loopback_ipv4_pool }}
  • {{ switch_id }}
  • {{ loopback_ipv4_offset }}
  • All group/hostvars

While all templates can leverage the internal switch facts (switch.*) to customize the interface descriptions, the values are not part of the officially supported data models, and may change without notice.

Context for interface_descriptions templates

Caveat

In AVD 4.x, it is not possible to completely overwrite the description of the subinterfaces when uplink_type is set to p2p-vrfs. The string _vrf_<VRF> is always appended to the description.

To help format the custom interface descriptions, the following contextual variables are available to the custom templates:

underlay_ethernet_interfaces:

  • {{ link.peer }}
  • {{ link.peer_interface }}
  • {{ link.type }} (underlay_p2p or underlay_l2)
  • All group/hostvars

underlay_port_channel_interfaces:

  • {{ link.channel_description }}
  • {{ link.channel_group_id }}
  • {{ link.peer }}
  • {{ link.peer_channel_group_id }}
  • All group/hostvars

mlag_ethernet_interfaces:

  • {{ mlag_interface }}
  • {{ mlag_peer }}
  • All group/hostvars

mlag_port_channel_interfaces:

  • {{ mlag_interfaces }} (list of strings)
  • {{ mlag_peer }}
  • {{ mlag_port_channel_id }}
  • All group/hostvars

connected_endpoints_ethernet_interfaces:

  • {{ peer }}
  • {{ peer_interface }}
  • {{ adapter_description }}
  • All group/hostvars

connected_endpoints_port_channel_interfaces:

  • {{ peer }}
  • {{ adapter_port_channel_id }}
  • {{ adapter_port_channel_description }}
  • {{ adapter_description }}
  • All group/hostvars

router_id_loopback_interfaces (replacing overlay_loopback_interface):

  • {{ router_id_loopback_description }}
  • {{ overlay_loopback_description }} (deprecated - use router_id_loopback_description instead)
  • All group/hostvars

vtep_loopback_interface:

  • {{ vtep_loopback_description }}
  • All group/hostvars

While all templates can leverage the internal switch facts (switch.*) to customize the interface descriptions, the values are not part of the officially supported data models and may change without notice.

Type setting

  • The type: variable needs to be defined for each device in the fabric.
  • This is leveraged to load the appropriate settings to generate the configuration.

Tip

The node type setting can be automatically derived from a switch name by defining the patterns in the default_node_types data model.

Type setting example
# Defined in SPINE.yml file
# Can also be set directly in your inventory file under spine group
type: spine

# Defined in L3LEAFS.yml
# Can also be set directly in your inventory file under l3leaf group
type: l3leaf

# Defined in L2LEAFS.yml
# Can also be set directly in your inventory file under l2leaf group
type: l2leaf

# Defined in SUPER-SPINES.yml
# Can also be set directly in your inventory file under super-spine group
type: super-spine

# Defined in ROUTE-SERVERS.yml
# Can also be set directly in your inventory file under route-server group
type: overlay-controller
Variable Type Required Default Value Restrictions Description
type String Valid Values:
-
-
The type: variable needs to be defined for each device in the fabric.
This is leveraged to load the appropriate template to generate the configuration.
# The `type:` variable needs to be defined for each device in the fabric.
# This is leveraged to load the appropriate template to generate the configuration.
type: <str; "<value(s) of custom_node_type_keys.type>" | "<value(s) of node_type_keys.type>">

Default node types settings

Node types can be defined statically on each node or in each group of nodes. By leveraging default_node_types, regular expressions can be used to determine the node type based on the hostname.

Warning

Please note that using the default_node_types functionality will cause certain tests in the eos_validate_state role to not be executed. This functionality will be restored as part of a later update to eos_validate_state and this note will then be removed.

Variable Type Required Default Value Restrictions Description
default_node_types List, items: Dictionary Uses hostname matches against a regular expression to determine the node type.
  - node_type String Required, Unique Resulting node type when regex matches.
    match_hostnames List, items: String Required Regular expressions to match against hostnames.
      - <str> String Required Regex needs to match full hostname (i.e. is bounded by ^ and $ elements).
# Uses hostname matches against a regular expression to determine the node type.
default_node_types:

    # Resulting node type when regex matches.
  - node_type: <str; required; unique>

    # Regular expressions to match against hostnames.
    match_hostnames: # required

        # Regex needs to match full hostname (i.e. is bounded by ^ and $ elements).
      - <str; required>

Node type settings

Node type settings are defined under the node_type_keys.key i.e spine:, l3leaf:, l2leaf: to configure management, underlay, overlay functionality.

Node type structure

All node types have the same structure based on defaults, node_group, node_group.node, node and all variables can be defined in any section and support inheritance like this:

Under node_type_keys.key:

defaults <- node_group <- node_group.node <- node

Tip

Define common node settings under defaults. This reduces user input requirements, limiting errors.

Node type common configuration

Define your nodes, id, management and common configuration elements.

Tip

If a node is not deployed, leverage is_deployed: false to indicate the node as offline.

Info

A static unique identifier (id) is assigned to each device. This is leveraged to derive the IP address assignment from each summary defined in the Fabric Underlay and Overlay Topology Variables.

Node type inband management

Variable Type Required Default Value Restrictions Description
<node_type_keys.key> Dictionary
  defaults Dictionary Define variables for all nodes of this type.
    inband_mgmt_interface String Pointer to interface used for inband management.
All configuration must be done using other data models like network services or structured_config.
‘inband_mgmt_interface’ is only used to refer to this interface as source in various management protocol settings (future feature).

On L2 switches, this defaults to Vlan if either ‘inband_mgmt_subnet’ or ‘inband_mgmt_ip’ is set.
    inband_mgmt_vlan Integer 4092 VLAN number used for inband management on L2 switches (switches using port-channel trunks as uplinks).
When using ‘inband_mgmt_subnet’ the VLAN and SVIs will be created automatically on this switch as well as all ‘uplink_switches’.
When using ‘inband_mgmt_ip’ the VLAN and SVI will only be created on this device and added to uplink trunk. The VLAN and SVI on the parent switches must be created using network services data models.
    inband_mgmt_subnet String Format: ipv4_cidr Optional IP subnet assigned to inband management SVIs on L2 switches (switches using port-channels as uplinks).
Parent l3leafs will have SVI with “ip virtual-router” and host-route injection based on ARP.
This allows all l3leafs to reuse the same subnet across multiple racks without VXLAN extension.
SVI IP address will be assigned as follows:
virtual-router: + 1
l3leaf A : + 2 (same IP on all l3leaf A)
l3leaf B : + 3 (same IP on all l3leaf B)
l2leafs : + 3 +
GW on l2leafs : + 1
Assign range larger than total l2leafs + 5

Setting is ignored if ‘inband_mgmt_ip’ is set.

This setting is applicable to L2 switches (switches using port-channel trunks as uplinks).
    inband_mgmt_ip String Format: ipv4_cidr IP address assigned to the inband management interface set with ‘inband_mgmt_vlan’.
This overrides ‘inband_mgmt_subnet’, hence all behavior of ‘inband_mgmt_subnet’ is removed.

If this is set the VLAN and SVI will only be created on the L2 switch and added to uplink trunk.
The VLAN and SVI on the parent switches must be created using network services data models.

This setting is applicable to L2 switches (switches using port-channel trunks as uplinks).
    inband_mgmt_gateway String Format: ipv4 Default gateway configured in the ‘inband_mgmt_vrf’ when using ‘inband_mgmt_ip’. Otherwise gateway is derived from ‘inband_mgmt_subnet’ if set.

This setting is applicable to L2 switches (switches using port-channel trunks as uplinks).
    inband_mgmt_ipv6_address String Format: ipv6 IPv6 address assigned to the inband management interface set with ‘inband_mgmt_vlan’.
This overrides ‘inband_mgmt_ipv6_subnet’, hence the configuration of ‘inband_mgmt_ipv6_subnet’ is ignored.

If this is set the VLAN and SVI will only be created on the L2 switch and added to uplink trunk.
The VLAN and SVI on the parent switches must be created using network services data models.

This setting is applicable to L2 switches (switches using port-channel trunks as uplinks).
    inband_mgmt_ipv6_subnet String Format: ipv6_cidr Optional IPv6 prefix assigned to inband management SVIs on L2 switches (switches using port-channels as uplinks).
Parent l3leafs will have SVI with “ipv6 virtual-router” and host-route injection based on ARP.
This allows all l3leafs to reuse the same subnet across multiple racks without VXLAN extension.
SVI IP address will be assigned as follows:
virtual-router: + 1
l3leaf A : + 2 (same IP on all l3leaf A)
l3leaf B : + 3 (same IP on all l3leaf B)
l2leafs : + 3 +
GW on l2leafs : + 1
Assign range larger than total l2leafs + 5

Setting is ignored if ‘inband_mgmt_ipv6_address’ is set.

This setting is applicable to L2 switches (switches using port-channel trunks as uplinks).
    inband_mgmt_ipv6_gateway String Format: ipv6 Default gateway configured in the ‘inband_mgmt_vrf’.
Used when inband_mgmt_ipv6_address is set.
Ignored when ‘inband_mgmt_ipv6_subnet’ is set (first IP in subnet used as gateway).

This setting is applicable to L2 switches (switches using port-channel trunks as uplinks).
    inband_mgmt_description String Inband Management Description configured on the Inband Management SVI.

This setting is only applied on the devices where it is set, it does not automatically affect any parent/child devices configuration, so it must be set on each applicable node/node-group/node-type as needed.
    inband_mgmt_vlan_name String Inband Management Name configured on the Inband Management VLAN.
This setting is only applied on the devices where it is set, it does not automatically affect any parent/child devices configuration, so it must be set on each applicable node/node-group/node-type as needed.
    inband_mgmt_vrf String default VRF configured on the Inband Management Interface.

Tip

Leverage default_interfaces data model to auto define uplink and downlink interfaces based on the node id.

Variable Type Required Default Value Restrictions Description
<node_type_keys.key> Dictionary
  defaults Dictionary Define variables for all nodes of this type.
    link_tracking Dictionary This configures the Link Tracking Group on a switch as well as adds the p2p-uplinks of the switch as the upstream interfaces.
Useful in EVPN multhoming designs.
      enabled Boolean False
      groups List, items: Dictionary [{'name': 'LT_GROUP1'}] Link Tracking Groups.
By default a single group named “LT_GROUP1” is defined with default values.
Any groups defined under “groups” will replace the default.
        - name String Tracking group name.
          recovery_delay Integer Min: 0
Max: 3600
default -> platform_settings_mlag_reload_delay -> 300.
          links_minimum Integer Min: 1
Max: 100000
    uplink_type String p2p Valid Values:
- p2p
- port-channel
- p2p-vrfs
- lan
Override the default uplink_type set at the node_type_key level.
uplink_type must be “p2p” if vtep or underlay_router is true for the node_type_key definition.
    uplink_ipv4_pool String Format: ipv4_cidr IPv4 subnet to use to connect to uplink switches.
    uplink_interfaces List, items: String Local uplink interfaces.
Each list item supports range syntax that can be expanded into a list of interfaces.
If uplink_interfaces is not defined, platform-specific defaults (defined under default_interfaces) will be used instead.
Please note that default_interfaces are not defined by default, you should define these yourself.
      - <str> String Pattern: Ethernet[\d/]+
    uplink_switch_interfaces List, items: String Interfaces located on uplink switches.
      - <str> String Pattern: Ethernet[\d/]+
    uplink_switches List, items: String
      - <str> String Required Hostname of uplink switch.
If parallel uplinks are in use, update max_parallel_uplinks below and specify each uplink switch multiple times.
e.g. uplink_switches: [ ‘DC1-SPINE1’, ‘DC1-SPINE1’, ‘DC1-SPINE2’, ‘DC1-SPINE2’ ].
    uplink_interface_speed String Set point-to-Point interface speed and will apply to uplink interfaces on both ends.
(Uplink switch interface speed can be overridden with uplink_switch_interface_speed).
Speed should be set in the format <interface_speed> or forced <interface_speed> or auto <interface_speed>.
    uplink_switch_interface_speed String Set point-to-Point interface speed for the uplink switch interface only.
Speed should be set in the format <interface_speed> or forced <interface_speed> or auto <interface_speed>.
    uplink_mtu Integer Min: 68
Max: 65535
Point-to-Point uplinks MTU in bytes. This setting overrides the p2p_uplinks_mtu setting.
    max_uplink_switches Integer Maximum number of uplink switches.
Changing this value may change IP Addressing on uplinks.
Can be used to reserve IP space for future expansions.
    max_parallel_uplinks Integer Number of parallel links towards uplink switches.
Changing this value may change interface naming on uplinks (and corresponding downlinks).
Can be used to reserve interfaces for future parallel uplinks.
    uplink_bfd Boolean False Enable bfd on uplink interfaces.
    uplink_native_vlan Integer Min: 1
Max: 4094
Only applicable to switches with layer-2 port-channel uplinks.
A suspended (disabled) vlan will be created in both ends of the link unless the vlan is defined under network services.
By default the uplink will not have a native_vlan configured, so EOS defaults to vlan 1.
    uplink_ptp Dictionary Enable PTP on all infrastructure links.
      enable Boolean False
    uplink_macsec Dictionary Enable MacSec on all uplinks.
      profile String
    uplink_port_channel_id Integer Min: 1
Max: 999999
Only applicable for L2 switches with uplink_type: port-channel.
By default the uplink Port-channel ID will be set to the number of the lowest member interface defined under uplink_interfaces.
For example:
member ports [ Eth22, Eth23 ] -> ID 22
member ports [ Eth11/1, Eth22/1 ] -> ID 111
For MLAG port-channels ID will be based on the lowest member interface on the first MLAG switch.
This option overrides the default behavior and statically sets the local Port-channel ID.
Note! Make sure the ID is unique and does not overlap with autogenerated Port-channel IDs in the Network Services.
Note! For MLAG pairs the ID must be between 1 and 2000 and both MLAG switches must have the same value.
    uplink_switch_port_channel_id Integer Min: 1
Max: 999999
Only applicable for L2 switches with uplink_type: port-channel.
By default the uplink switch Port-channel ID will be set to the number of the first interface defined under uplink_switch_interfaces.
For example:
member ports [ Eth22, Eth23 ] -> ID 22
member ports [ Eth11/1, Eth22/1 ] -> ID 111
For MLAG port-channels ID will be based on the lowest member interface on the first MLAG switch.
This option overrides the default behavior and statically sets the Port-channel ID on the uplink switch.
Note! Make sure the ID is unique and does not overlap with autogenerated Port-channel IDs in the Network Services.
Note! For MLAG pairs the ID must be between 1 and 2000 and both MLAG switches must have the same value.
    uplink_structured_config Dictionary Custom structured config applied to “uplink_interfaces”, and “uplink_switch_interfaces”.
When uplink_type == “p2p”, custom structured config added under ethernet_interfaces.[name=] for eos_cli_config_gen overrides the settings on the ethernet interface level.

- client
- server
Override the default WAN role.

This is used both for AutoVPN and Pathfinder designs.
That means if wan_mode root key is set to autovpn or cv-pathfinder.
server indicates that the router is a route-reflector.

Only supported if overlay_routing_protocol is set to ibgp.
    cv_pathfinder_transit_mode String Valid Values:
- region
- zone
Configure the transit mode for a WAN client for CV Pathfinder designs
only when the wan_mode root key is set to cv_pathfinder.

‘zone’ is currently not supported.
    cv_pathfinder_region String The CV Pathfinder region name.
This key is required for WAN routers but optional for pathfinders.
The region name must be defined under ‘cv_pathfinder_regions’.
    cv_pathfinder_site String The CV Pathfinder site name.
This key is required for WAN routers but optional for pathfinders.
For WAN routers and pathfinders with cv_pathfinder_region, the site name must be defined for the relevant region under ‘cv_pathfinder_regions’.
For pathfinders without cv_pathfinder_region set, the site must be defined under cv_pathfinder_global_sites.
    wan_ha Dictionary PREVIEW: This key is currently not supported

The key is supported only if wan_mode == cv-pathfinder.
AutoVPN support is still to be determined.

Maximum 2 devices supported by group for HA.
      enabled Boolean True Enable / Disable auto CV-Pathfinder HA, when two nodes are defined in the same node_group.
      ipsec Boolean True Enable / Disable IPsec over HA path-group when HA is enabled.

Max: 65535
Set MTU on WAN HA interfaces.
      ha_interfaces List, items: String Local WAN HA interfaces
Overwrite the default behavior which is to pick all the uplink_interfaces.
Can be used to filter uplink interfaces when there are multiple uplinks.
Limitations:
Either all interfaces must be uplinks or all interfaces must not be uplinks.

Default interface settings

  • Set default uplink, downlink, and MLAG interfaces, which will be used if these interfaces are not defined on a device (either directly or through inheritance).
  • These are defined based on the combination of node_type (e.g., l3leaf or spine) and a regex for matching the platform.
  • A list of interfaces or interface ranges can be specified.
  • Each list item supports range syntax that can be expanded into a list of interfaces. Interface range examples:
    • Ethernet49-52/1: Expands to [ Ethernet49/1, Ethernet50/1, Ethernet51/1, Ethernet52/1 ]
    • Ethernet1/31-34/1: Expands to [ Ethernet1/31/1, Ethernet1/32/1, Ethernet1/33/1, Ethernet1/34/1 ]
    • Ethernet49-50,53-54: Expands to [ Ethernet49, Ethernet50, Ethernet53, Ethernet54 ]
    • Ethernet1-2/1-4: Expands to [ Ethernet1/1, Ethernet1/2, Ethernet1/3, Ethernet1/4, Ethernet2/1, Ethernet2/2, Ethernet2/3, Ethernet2/4 ]
  • uplink_interfaces and mlag_interfaces under default_interfaces are directly inherited by uplink_interfaces and mlag_interfaces.
  • downlink_interfaces are referenced by the child switch (e.g., the leaf in a leaf/spine network). The child switch leverages an upstream switch’s default_downlink_interfaces using the child switch ID. This is then used to build uplink_switch_interfaces for that child.
    • In the case of max_parallel_uplinks > 1 the default_downlink_interfaces are mapped with consecutive downlinks per child ID.
    • Example for max_parallel_uplinks: 2, downlink interfaces will be mapped as [ <downlink1 to leaf-id1>, <downlink2 to leaf-id1>, <downlink1 to leaf-id2>, <downlink2 to leaf-id2> ...]
  • Please note that no default interfaces are defined in AVD itself. You will need to create your own based on the example below.

L3 edge and DCI settings

The l3_edge data model can be used to configure extra L3 P2P links anywhere in the fabric. It can be between two switches that are already part of the fabric inventory, or it can be towards another device, where only one end of the link is on a switch in the fabric.

The data model supports using IP pools, Subnet per link, specifying the IP addresses manually or using ipv6 with rfc5549. One of these options must be set. For BGP peerings the AS number must be specified. If the AS number is different than the AS number configured for the node, the local-as will be replaced on this BGP peering (neighbor <ip> local-as <as> no-prepend replace-as).

Make sure to configure the variables in a group_vars file covering all devices mentioned in the data model.

Core interfaces settings

The core_interfaces data model can be used to configure L3 P2P links anywhere in the fabric. It can be between two switches that are already part of the fabric inventory, or it can be towards another device, where only one end of the link is on a switch in the fabric.

The data model supports using IP pools, Subnet per link or specifying the IP addresses manually. For BGP peerings the AS number must be specified. If the AS number is different than the AS number configured for the node, the local-as will be replaced on this BGP peering (neighbor <ip> local-as <as> no-prepend replace-as).

Make sure to configure the variables in a group_vars file covering all devices mentioned in the data model.

Flagging a device as not deployed

  • It is possible to provision configurations for a complete topology but flag devices as undeployed using the host level variable is_deployed: false.
  • By default, this will have no impact within the eos_designs role. Configs will still be generated by the eos_cli_config_gen role and will still be pushed by the eos_config_deploy_eapi directly to devices if used.
  • However, if the eos_config_deploy_cvp role is used to push configurations, CloudVision will ignore the devices flagged as is_deployed: false and not attempt to configure them.
  • If the device is not present in the network due to CloudVision not configuring the device, eos_validate_state role will fail lldp_toplogy and interface tests on peers of the undeployed device trying to verify that interfaces are up.
  • To overcome this and shutdown interfaces towards undeployed peers, the variable shutdown_interfaces_towards_undeployed_peers can be used, satisfying the eos_validate_state role interface and lldp_topology tests. Again, this is only an issue if eos_config_deploy_cvp is used and the devices are not present in the network.
Variable Type Required Default Value Restrictions Description
is_deployed Boolean True If the device is already deployed in the fabric.
When set to false, interfaces toward this device may be shutdown depending on the shutdown_interfaces_towards_undeployed_peers setting.
Furthermore eos_config_deploy_cvp will not attempt to move or apply configurations to the device.
# If the device is already deployed in the fabric.
# When set to false, interfaces toward this device may be shutdown depending on the `shutdown_interfaces_towards_undeployed_peers` setting.
# Furthermore `eos_config_deploy_cvp` will not attempt to move or apply configurations to the device.
is_deployed: <bool; default=True>

Fabric settings

The following underlay routing protocols are supported:

  • EBGP (default for l3ls-evpn)
  • OSPF.
  • ISIS.
  • ISIS-SR*.
  • ISIS-LDP*.
  • ISIS-SR-LDP*.
  • OSPF-LDP*.
  • none**.

* Only supported with core_interfaces data model.
** For use with design type “l2ls” or other designs where there is no requirement for a routing protocol for underlay and/or overlay on l3 devices.

Details on enable_trunk_groups

Enabling the use of trunk groups will change the behavior of several components in AVD.

Changes:

  • Requires Trunk Groups to be defined on all trunks towards connected endpoints
  • MLAG Trunk Group will be configured on all vlans on MLAG switches
  • Use Trunk Groups for uplinks to L2 switches instead of “switchport trunk allow vlan” lists.
    • On the parent switch a Trunk Group with the name of the L2 switch will be assigned on all vlans that are allowed towards the L2 switch.
    • The port-channel towards the L2 switch will be assigned to this trunk group only
    • Add UPLINK Trunk Group to all vlans on the L2 Switch and assign this to the uplink port-channel

Figure: Enable Trunk Groups

While it is recommended for consistency to set enable_trunk_groups for all devices in the fabric, it can also be set in group_vars or host_vars since trunk-groups are only local to a switch.

Warning

Because of the nature of the EOS Trunk Group feature, enabling this is “all or nothing”. All vlans and all trunks towards connected endpoints must be using trunk groups as well. If trunk groups are not assigned to a trunk, no vlans will be enabled on that trunk.

Details on only_local_vlan_trunk_groups

Enabling this feature will prevent unneeded trunk groups from being configured on vlans.

Using the figure under Details on enable_trunk_groups as basis enabling with feature would remove the unmatched trunk groups like this:

Figure: Enable only_local_vlan_trunk_groups

Overlay settings

The following overlay routing protocols are supported:

  • EBGP (default for l3ls-evpn)
  • IBGP (only with OSPF or ISIS variants in underlay)
  • none*
  • HER (Head-End Replication)**
  • CVX (CloudVision eXchange)

* For use with design type “l2ls” or other designs where there is no requirement for a routing protocol for underlay and/or overlay on l3 devices.
** By setting overlay_routing_protocol:HER, eos_designs will configure static VXLAN flood-lists instead of using a dynamic overlay protocol.

Variable Type Required Default Value Restrictions Description
bgp_mesh_pes Boolean False Configure an iBGP full mesh between PEs, either because there is no RR used or other reasons.
Only supported in combination with MPLS overlay.
overlay_bgp_peer_description String {peer}{peer_interface?<_} Description or description template to be used on the overlay BGP peers.
This can be a template using the AVD string formatter syntax: https://avd.arista.com/devel/roles/eos_designs/docs/how-to/custom-descriptions-names.html#avd-string-formatter-syntax.
The available template fields are:
- peer: The name of the BGP peer.
- peer_interface: The interface on the BGP peer if available.

The default description is built from the name and interface of the BGP peer.
overlay_cvx_servers List, items: String List of CVX vxlan overlay controllers.
Required if overlay_routing_protocol == CVX.
CVX servers (VMs) are peering using their management interface, so mgmt_ip must be set for all CVX servers.
  - <str> String ‘inventory_hostname’ of CVX server.
overlay_her_flood_list_per_vni Boolean False When using Head-End Replication, configure flood-lists per VNI.
By default HER will be configured with a common flood-list containing all VTEPs.
This behavior can be changed to per-VNI flood-lists by setting overlay_her_flood_list_per_vni: true.
This will make eos_designs consider configured VLANs per VTEP, and only include the relevant VTEPs to each VNI’s flood-list.
overlay_her_flood_list_scope String fabric Valid Values:
- fabric
- dc
When using Head-End Replication, set the scope of flood-lists to Fabric or DC.
By default all VTEPs in the Fabric (part of the inventory group referenced by “fabric_name”) are added to the flood-lists.
This can be changed to all VTEPs in the DC (sharing the same “dc_name” value).
This is useful if Border Leaf switches are dividing the VXLAN overlay into separate domains.
overlay_loopback_description deprecated String Customize the description on overlay interface Loopback0.This key is deprecated. Support will be removed in AVD version 6.0.0. Use router_id_loopback_description instead.
overlay_mlag_rfc5549 Boolean False IPv6 Unnumbered for MLAG iBGP connections.
Requires “underlay_rfc5549: true”.
overlay_rd_type Dictionary Configuration options for the Administrator subfield (first part of RD) and the Assigned Number subfield (second part of RD).

By default Route Distinguishers (RD) are set to:
- <overlay_loopback>:<mac_vrf_id_base + vlan_id or mac_vrf_vni_base + vlan_id> for VLANs and VLAN-Aware Bundles with L2 vlans.
- <overlay_loopback>:<vlan_aware_bundle_number_base + vrf_id> for VLAN-Aware Bundles with SVIs.
- <overlay_loopback>:<vlan_aware_bundle_number_base + id> for VLAN-Aware Bundles defined under ‘evpn_vlan_bundles’.
- <overlay_loopback>:<vrf_id> for VRFs.

Note:
RD is a 48-bit value which is split into <16-bit>:<32-bit> or <32-bit>:<16-bit>.
When using loopback or 32-bit ASN/number the assigned number can only be a 16-bit number. This may be a problem with large VNIs.
For 16-bit ASN/number the assigned number can be a 32-bit number.
  admin_subfield String router_id The method for deriving RD Administrator subfield (first part of RD):
- ‘router_id’ means the IP address of Loopback0.
- ‘vtep_loopback’ means the IP address of the VTEP loopback interface.
- ‘bgp_as’ means the AS number of the device.
- ‘switch_id’ means the ‘id’ value of the device.
- Any without mask.
- Integer between <0-65535>.
- Integer between <0-4294967295>.
- ‘overlay_loopback_ip’ means the IP address of Loopback0. (deprecated - use ‘router_id’ instead)
  admin_subfield_offset String Offset can only be used if admin_subfield is an integer between <0-4294967295> or ‘switch_id’.
Total value of admin_subfield + admin_subfield_offset must be <= 4294967295.
  vrf_admin_subfield String The method for deriving RD Administrator subfield (first part of RD) for VRF services:
- ‘router_id’ means the IP address of Loopback0.
- ‘vtep_loopback’ means the IP address of the VTEP loopback interface.
- ‘bgp_as’ means the AS number of the device.
- ‘switch_id’ means the ‘id’ value of the device.
- Any without mask.
- Integer between <0-65535>.
- Integer between <0-4294967295>.
- ‘overlay_loopback_ip’ means the IP address of Loopback0. (deprecated - use ‘router_id’ instead)

‘vrf_admin_subfield’ takes precedence for VRF RDs if set. Otherwise the ‘admin_subfield’ value will be used.
  vrf_admin_subfield_offset String Offset can only be used if ‘vrf_admin_subfield’ is an integer between <0-4294967295> or ‘switch_id’.

Endpoint connectivity

AVD supports two different data models for defining connectivity to endpoints:

  • “Connected Endpoints” is an endpoint-centric model intended for servers or other use cases where most ports have unique configurations.
  • “Network Ports” is a compact and port-centric model intended for configuration of generic port configurations on large ranges of ports.

Both data models share the same underlying implementation and can coexist without conflicts. If a switch port is defined in both “Connected Endpoints” and “Network Ports”, the “Connected Endpoints” configuration will take precedence.

Both data models support variable inheritance from profiles defined under port_profiles. The profiles can be shared between the models. Any setting defined under the port_profiles will be inherited from parent_profile to profile to adapter.

Connected endpoints settings

  • The connected endpoints variables define connectivity from the perspective of the endpoints that connect to the fabric.
  • Each endpoint can have one or more adapters defined, under which the connected switches, switch_ports and endpoint_ports must be set.
  • If port_channel mode is enabled under one “adapter”, all switch_ports connected to that “adapter” will become part of this port-channel.
  • The keys used to define connected endpoints are configurable using connected_endpoints_keys. The default available keys are:
    • servers
    • firewalls
    • routers
    • load_balancers
    • storage_arrays
    • cpes
    • workstations
    • access_points

Example with EVPN A/A ESI dual-attached endpoint

To help provide consistency when configuring EVPN A/A ESI values, arista.avd provides an abstraction in the form of a short_esi key. short_esi is an abbreviated 3 octets value to encode Ethernet Segment ID and LACP ID.

The abstracted short_esi: "0303:0202:0101" is transformed into the following network values:

  • EVPN ESI: 0000:0000:0303:0202:0101
  • LACP ID: 0303.0202.0101
  • Route Target: 03:03:02:02:01:01

In addition, setting the short_esi key to auto generates the short_esi automatically using a hash of the following data elements:

  • Port-Channel Interfaces: first two uplink switch hostnames, the ports on those switches, the corresponding endpoint ports and the channel-group ID.
  • Port-Channel Subinterface: first two uplink switch hostname, the ports on those switches, the corresponding endpoint ports, the channel-group ID and the subinterface number.
  • Ethernet Interfaces: first two uplink switch hostnames, the ports on those switches, the corresponding endpoint ports and the interface number.

It should be noted that arista.avd does not currently check for hash collisions when using short_esi: auto and while the risk of this happening is non-zero, it is small.

        ethernet_segment Dictionary Settings for all or single-active EVPN multihoming.
          short_esi String Required In format xxxx:xxxx:xxxx or “auto”.
Define a manual short-esi (be careful using this on profiles) or set the value to “auto” to automatically generate the value.
Please see the notes under “EVPN A/A ESI dual and single-attached endpoint scenarios” before setting short_esi: auto.
          redundancy String Valid Values:
- all-active
- single-active
If omitted, Port-Channels use the EOS default of all-active.
If omitted, Ethernet interfaces are configured as single-active.
          designated_forwarder_algorithm String Valid Values:
- auto
- modulus
- preference
Configure DF algorithm and preferences.
- auto: Use preference-based algorithm and assign preference based on position of device in the ‘switches’ list,
e.g., assuming a list of three switches, this would assign a preference of 200 to the first switch, 100 to the 2nd, and 0 to the third.
- preference: Set preference for each switch manually using designated_forwarder_preferences key.
- modulus: Use the default modulus-based algorithm.
If omitted, Port-Channels use the EOS default of modulus.
If omitted, Ethernet interfaces default to the ‘auto’ mechanism detailed above.
          designated_forwarder_preferences List, items: Integer Manual preference as described above, required only for preference algorithm.
            - <int> Integer
          dont_preempt Boolean Disable preemption for single-active forwarding when auto/manual DF preference is configured.

          mode String Valid Values:
- active
- passive
- on
Port-Channel Mode.
          channel_id Integer Port-Channel ID.
If no channel_id is specified, an id is generated from the first switch port in the port channel.
          description String Description or description template to be used on the port-channel interface.
This can be a template using the AVD string formatter syntax: https://avd.arista.com/devel/roles/eos_designs/docs/how-to/custom-descriptions-names.html#avd-string-formatter-syntax.
The available template fields are:
- endpoint_type - the type from connected_endpoints_keys like server, router etc.
- endpoint - The name of the connected endpoint
- endpoint_port_channel - The value from endpoint_port_channel if set.
- port_channel_id - The port-channel number for the switch.
- adapter_description - The adapter’s description if set.
- adapter_description_or_endpoint - Helper alias of the adapter_description or endpoint.

The default description is set by default_connected_endpoints_port_channel_description.
By default the description is templated from the type, name and port_channel interface of the endpoint if set.
          endpoint_port_channel String Name of the port-channel interface on the endpoint.
Used for the port-channel description template with the field name peer_interface
          enabled Boolean True Port-Channel administrative state.
Setting to false will set port to ‘shutdown’ in intended configuration.
          ptp_mpass Boolean False When MPASS is enabled on an MLAG port-channel, MLAG peers coordinate to function as a single PTP logical device.
Arista PTP enabled devices always place PTP messages on the same physical link within the port-channel.
Hence, MPASS is needed only on MLAG port-channels connected to non-Arista devices.
          lacp_fallback Dictionary LACP fallback configuration.
            mode String Valid Values:
- static
- individual
Either static or individual mode is supported.
If the mode is set to “individual” the “individual.profile” setting must be defined.

- normal
- fast
LACP mode for interface members.
            multiplier Integer Number of LACP BPDUs lost before deeming the peer down. EOS default is 3.
          subinterfaces List, items: Dictionary Port-Channel L2 Subinterfaces
Subinterfaces are only supported on routed port-channels, which means they cannot be configured on MLAG port-channels.
Setting short_esi: auto generates the short_esi automatically using a hash of configuration elements.
Please see the notes under “EVPN A/A ESI dual-attached endpoint scenario” before setting short_esi: auto.
            - number Integer Subinterface number.
              short_esi String In format xxxx:xxxx:xxxx or “auto”.

Network ports settings

The network_ports data model is intended to be used with port_profiles and parent_profiles to keep the configuration generic and compact, but all features and keys supported under connected_endpoints.adapters are also supported directly under network_ports.

All ranges defined under switch_ports will be expanded to individual port configuration which leads to a some behavioral differences to connected_endpoints:

  • By default each port will be configured in a port-channel with one member when leveraging automatic channel-id generation. To configure multiple ports as member of the same port-channel set the channel-id key (see the example below).
  • Inconsistent configurations when used with short_esi: auto or designated_forwarder_algorithm: auto, since those rely on information from multiple switches and interfaces.
Example using network ports and profiles
# Port Profiles
# Common settings inherited to network_ports
port_profiles:
  - profile: common
    mode: access
    vlans: "999"
    spanning_tree_portfast: edge
    spanning_tree_bpdufilter: enabled

  - profile: ap_with_port_channel
    parent_profile: common
    vlans: "101"
    port_channel:
      mode: active

  - profile: pc
    parent_profile: common
    vlans: "100"

# Network Ports
# All switch_ports ranges are expanded into individual port configurations
# Switches are matched with regex matching the full hostname.
network_ports:
  - switches:
      - network-ports-tests-1
    switch_ports:
      - Ethernet1-2
    profile: pc
    endpoint: PCs

  - switches:
      - network-ports-tests-2$
    switch_ports:
      - Ethernet1-2
    profile: ap_with_port_channel
    endpoint: AP1 with port_channel

  - switches:
      - network-ports-[est]{5}-.*
    switch_ports:
      - Ethernet3-4
      - Ethernet2/1-48
    profile: pc
    endpoint: PCs
Example using network ports to configure multiple ports in the same port-channel

When defining port-channels, all ranges defined under switch_ports will be expanded to individual port configurations in a port-channel with one member. To configure multiple ports as members of the same port-channel, set the channel-id key manually like in this example:

# Network Ports
# By setting the channel_id key under port-channel, interfaces Ethernet3-4 will
# be configured under the same port-channel.
network_ports:
  - switches:
      - network-ports-tests-1
    switch_ports:
      - Ethernet3-4
    description: Multiple interfaces in the same port-channel
    port_channel:
      mode: active
      channel_id: 42

This will generate the following config:

interface Port-Channel42
  description Multiple interfaces in the same port-channel
  no shutdown
  switchport
!
!
interface Ethernet3
  description Multiple interfaces in the same port-channel
  no shutdown
  channel-group 42 mode active
!
interface Ethernet4
  description Multiple interfaces in the same port-channel
  no shutdown
  channel-group 42 mode active
!

Tip

To leverage automatic channel-id computation and configure port-channel with multiple members, connected_endpoints should be used.

Connected endpoints keys settings

The keys used to define Connected Endpoints are configurable using connected_endpoints_keys.

Endpoints connecting to the fabric can be grouped by using separate keys. The keys can be customized to provide a better better organization or grouping of your data.

connected_endpoints_keys should be defined in the top level group_vars for the fabric.

Note

The default values will be overridden if defining this key, so it is recommended to copy the defaults and modify them.

Network Services

The network services variables provide an abstracted model to define network services across the fabric. The network services are grouped by tenants. The definition of a tenant may vary between organizations. E.g. tenants can be organizations or departments.

The filtering models defined under Node type network services configuration allows for granular deployment of network services to the fabric leveraging the tenant name and tags applied to the service definition.

  • This allows for the reuse of SVI/VLAN IDs across the fabric.
  • An error will be returned at runtime in case of duplicate or conflicting SVI/VLAN IDs or VNIs targeted towards the same device.

Network services settings

The supported network services for each tenant cover:

  • VRFs
    • SVIs
    • L3 Interfaces
    • Loopbacks
    • BGP routing
    • OSPF routing
  • L2 VLANs
  • Point-to-point services (Pseudowires, only for MPLS designs)
  • Multicast

Typically services within each tenant share common VNI ranges and MAC VRF assignment pattern.

The keys used to define network services are configurable using network_services_keys. The default available keys is tenants.

By default an iBGP peering is configured per VRF between MLAG peers on separate VLANs.
Setting enable_mlag_ibgp_peering_vrfs false under a tenant will change this default to prevent configuration of these peerings and VLANs for all VRFs in the tenant.
This setting can be overridden per VRF.
    redistribute_mlag_ibgp_peering_vrfs Boolean False Redistribute the connected subnet for the MLAG iBGP peering per VRF into overlay BGP.
By default the iBGP peering subnet is not redistributed into the overlay routing protocol per VRF.
Setting redistribute_mlag_ibgp_peering_vrfs: true under a tenant will change this default to redistribution of these subnets for all VRFs in the tenant.
This setting can be overridden per VRF.
    vrfs List, items: Dictionary VRFs will only be configured on a node if any of the underlying objects like svis or l3_interfaces apply to the node.

It is recommended to only define a VRF in one Tenant. If the same VRF name is used across multiple tenants and those tenants
are accepted by filter.tenants on the node, any object set under the duplicate VRFs must either be unique or be an exact match.

VRF “default” is partially supported under network-services. Currently the supported options for “default” vrf are route-target,
route-distinguisher settings, structured_config, raw_eos_cli in bgp and SVIs are the only supported interface type.
Vlan-aware-bundles are supported as well inside default vrf. OSPF is not supported currently.

“vrf_vni” may also be used for VRF RD/RT ID. See “overlay_rd_type” and “overlay_rt_type” for details.
See “mlag_ibgp_peering_vrfs.base_vlan” for details.
If vrf_vni > 10000 make sure to adjust “mac_vrf_vni_base” accordingly to avoid overlap.
        vrf_id Integer Required if “vrf_vni” is not set.
“vrf_id” is used as default value for “vrf_vni” and “ospf.process_id” unless those are set.
“vrf_id” may also be used for VRF RD/RT ID. See “overlay_rd_type” and “overlay_rt_type” for details.
“vrf_id” is preferred over “vrf_vni” for MLAG iBGP peering vlan, see “mlag_ibgp_peering_vrfs.base_vlan” for details.
        rd_override String By default, the VRF RD will be derived from the pattern defined in overlay_rd_type.
The rd_override allows us to override this value and statically define it.

rd_override supports two formats:

It is recommended to only define a VRF in one Tenant. If the same VRF name is used across multiple tenants and those tenants
are accepted by filter.tenants on the node, any object set under the duplicate VRFs must either be unique or be an exact match.

VRF “default” is partially supported under network-services. Currently the supported options for “default” vrf are route-target,
route-distinguisher settings, structured_config, raw_eos_cli in bgp and SVIs are the only supported interface type.
Vlan-aware-bundles are supported as well inside default vrf. OSPF is not supported currently.

Network services VRF OSPF configuration

Variable Type Required Default Value Restrictions Description
<network_services_keys.name> List, items: Dictionary
  - name String Required, Unique Specify a tenant name.
Tenant provide a construct to group L3 VRFs and L2 VLANs.
Networks services can be filtered by tenant name.
    vrfs List, items: Dictionary VRFs will only be configured on a node if any of the underlying objects like svis or l3_interfaces apply to the node.

It is recommended to only define a VRF in one Tenant. If the same VRF name is used across multiple tenants and those tenants
are accepted by filter.tenants on the node, any object set under the duplicate VRFs must either be unique or be an exact match.

VRF “default” is partially supported under network-services. Currently the supported options for “default” vrf are route-target,
route-distinguisher settings, structured_config, raw_eos_cli in bgp and SVIs are the only supported interface type.
Vlan-aware-bundles are supported as well inside default vrf. OSPF is not supported currently.
      - name String Required, Unique
        ospf Dictionary Router OSPF configuration.
This will create an OSPF routing instance in the tenant VRF. If there is no nodes definition, the OSPF instance will be
created on all leafs where the VRF is deployed. This will also cause automatic OSPF redistribution into BGP unless
explicitly turned off with “redistribute_ospf: false”.
          enabled Boolean
          process_id Integer If not set, “vrf_id” will be used.

            - <str> String Hostname.
        redistribute_ospf Boolean True Non-selectively enabling or disabling redistribute ospf inside the VRF.
        svis List, items: Dictionary List of SVIs.
This will create both the L3 SVI and L2 VLAN based on filters applied to the node.
          - id Integer Required Min: 1
Max: 4096
SVI interface id and VLAN id.
            nodes List, items: Dictionary Define node specific configuration, such as unique IP addresses.
Any keys set here will be merged onto the SVI config, except structured_config keys which will replace the structured_config set on SVI level.

Tenant provide a construct to group L3 VRFs and L2 VLANs.
Networks services can be filtered by tenant name.
    evpn_l2_multicast Dictionary Enable EVPN L2 Multicast for all SVIs and l2vlans within Tenant.
- Multicast group binding is created only for Multicast traffic. BULL traffic will use ingress-replication.
- Configures binding between VXLAN, VLAN, and multicast group IPv4 address using the following formula:
< evpn_l2_multicast.underlay_l2_multicast_group_ipv4_pool > + < vlan_id - 1 > + < evpn_l2_multicast.underlay_l2_multicast_group_ipv4_pool_offset >.
- The recommendation is to assign a /20 block within the 232.0.0.0/8 Source-Specific Multicast range.
- Enables redistribute igmp on the router bgp MAC VRF.
- When evpn_l2_multicast.enabled is true for a VLAN or a tenant, “igmp snooping” and “igmp snooping querier” will always be enabled - overriding those individual settings.

By default redistribute igmp is only configured when evpn_l2_multicast is True and evpn_l3_multicast for the VRF is False.
Configuring redistribute igmp when both L2 and L3 EVPN Multicast is enabled will take up additional control-plane and data-plane resources,
but it is required to support forwarding of TTL=1 multicast traffic within the VLAN.
This can be overridden per SVI.
    evpn_l3_multicast Dictionary Enable L3 Multicast for all SVIs and l3vlans within Tenant.
- In the evpn-l3ls design type, this enables L3 EVPN Multicast (aka OISM)’.
- Multicast group binding for VRF is created only for Multicast traffic. BULL traffic will use ingress-replication.
- Configures binding between VXLAN, VLAN, and multicast group IPv4 address using the following formula:
< l3_multicast.evpn_underlay_l3_multicast_group_ipv4_pool > + < vrf_id - 1 > + < l3_multicast.evpn_underlay_l3_multicast_group_ipv4_pool_offset >.
- The recommendation is to assign a /20 block within the 232.0.0.0/8 Source-Specific Multicast range.
- If enabled on an SVI using the anycast default gateway feature, a diagnostic loopback (see below) MUST be configured to source IGMP traffic.
- Enables evpn multicast on the router bgp VRF.
- When enabled on an SVI:
- If switch is part of an MLAG pair, enables “pim ipv4 sparse-mode” on the SVI.
- If switch is standalone or A-A MH, enables “ip igmp” on the SVI.
- If “ip address virtual” is configured, enables “pim ipv4 local-interface” and uses the diagnostic Loopback defined in the VRF
- Requires evpn_multicast to also be set to true.

SVI profiles settings

SVI profiles can be leveraged to share common settings between SVIs.

  • Keys are the same as those used under SVI settings, except for the tags key.
  • Keys defined under SVIs take precedence.
  • Structured configuration is not merged recursively and will be taken directly from the most specific level in the following order:

    1. svi.nodes[inventory_hostname].structured_config
    2. svi_profile.nodes[inventory_hostname].structured_config
    3. svi_parent_profile.nodes[inventory_hostname].structured_config

Network services keys settings

Network Services can be grouped by using separate keys.

The keys can be customized to provide a better better organization or grouping of your data. network_services_keys should be defined in the top level group_vars for the fabric.

Note

The default values will be overridden if defining this key, so it is recommended to copy the defaults and modify them.

Platform settings

Set platform specific settings like TCAM profile and reload delay.

If the platform is not defined, it will load parameters from the platform tagged default.

Management interface is modified for specific platforms like modular platforms with dual supervisor support and container EOS.

Note

The reload delay values should be reviewed and tuned to the specific environment.

Note

The default values will be overridden if platform_settings is defined. If you need to replace all the default platforms, it is recommended to copy the defaults and modify them. If you need to add custom platforms, create them under custom_platform_settings; if named identically to default platform_settings entries, custom entries will replace the equivalent default entry.

Custom Structured Configuration

See the Custom Structured Configuration how-to for details.

Variable Type Required Default Value Restrictions Description
custom_structured_configuration_list_merge String append_rp Valid Values:
- replace
- append
- keep
- prepend
- append_rp
- prepend_rp
The List-merge strategy used when merging custom structured configurations.

This applies to all vars prefixed by prefixes in custom_structured_configuration_prefix
and all data under the various structured_config options.

The available list merge strategies:
- replace:
- Any list will be replaced with the list defined in custom structured configurations.
- append:
- Existing list items with the same “Primary key”-value will be updated.
- New items will be appended to the existing list (including duplicates).
- keep:
- Only set list if there is no existing list or existing list is None.
- prepend:
- Existing list items with the same “Primary key”-value will be updated.
- New items will be prepended to the existing list (including duplicates).
- append_rp:
- Existing list items with the same “Primary key”-value will be updated.
- New unique items will be appended to the existing list.
- prepend_rp:
- Existing list items with the same “Primary key”-value will be updated.
- New unique items will be prepended to the existing list.
custom_structured_configuration_prefix List, items: String ['custom_structured_configuration_'] Custom EOS Structured Configuration keys can be set on any group or host_var level using the name
of the corresponding eos_cli_config_gen key prefixed with content of custom_structured_configuration_prefix.

The content of Custom Structured Configuration variables will be merged with the structured config generated by the eos_designs role.

The merge is done recursively, so it is possible to update a sub-key of a variable set by eos_designs role already.

The merge follow these recursive merge strategies:
- New keys will be added for all types.
- Existing keys of type “List” with a “Primary key” set in the schema:
- Strategy can be changed with custom_structured_configuration_list_merge. Default strategy:
- Existing list items with the same “Primary key”-value will be updated.
- New unique items will be appended to the existing list
- Other keys of type “List” will have new unique items appended the the existing list.
- Existing keys of type “Dictionary” will recursively merge
- Other existing keys will be replaced.

CloudVision Topology settings

Generate AVD topology configurations directly from a given CloudVision topology.

This feature is intended to be used for the integration of AVD and CloudVision Studios.

The topology should be pulled from the CloudVision “Inventory and Topology Studio” inputs. Device IDs must be translated to hostnames.

This feature currently provides the following configurations based on the given CloudVision topology and default_interfaces:

  • uplink_switches
  • uplink_interfaces
  • uplink_switch_interfaces
  • mlag_interfaces
  • platform (if set)
  • mgmt_interface (if interface “ManagementX” is found in the list)

Note

Any derived configuration can be overridden by setting the key manually. Even keys set under node type defaults will take precedence over these derived configurations.

When using parallel links between the same devices for L3 uplinks it is important to set max_uplink_switches and max_parallel_uplinks to ensure consistent IP addressing.

cv_topology example

To use this feature set default_interfaces according to the intended design (see default_intefaces for details) and set use_cv_topology to true. Provide a full topology under cv_topology like this example:

use_cv_topology: true
cv_topology:
  - hostname: s2-spine2
    platform: vEOS-LAB
    interfaces:
      - name: Ethernet2
        neighbor: s2-leaf1
        neighbor_interface: Ethernet3
      - name: Ethernet3
        neighbor: s2-leaf2
        neighbor_interface: Ethernet3
      - name: Ethernet4
        neighbor: s2-leaf3
        neighbor_interface: Ethernet3
      - name: Ethernet5
        neighbor: s2-leaf4
        neighbor_interface: Ethernet3
      - name: Ethernet7
        neighbor: s2-brdr1
        neighbor_interface: Ethernet3
      - name: Ethernet8
        neighbor: s2-brdr2
        neighbor_interface: Ethernet3
      - name: Management0
        neighbor: 00:1c:73:aa:bb:cc
        neighbor_interface: Ethernet21
  - hostname: s1-spine1
