Support “port_channel” interface in “router_service_insertion” -> “connections” for Internet exit

[ashenoy-arista]

Enhancement summary

Need logic support in eos_cli_config_gen schema and jinja template to render “port_channel” interface in “router_service_insertion” -> “connections”

This will be useful to support Direct Internet exit configuration on cv-pathfinder wan routers using Port-Channel interface.

File: python-avd/pyavd/_eos_cli_config_gen/schema/schema_fragments/router_service_insertion.schema.yml
For eos_cli_config_gen schema, need to add attribute “port_channel_interface” (of type dict) under “router_service_insertion” -> “connections”
(similar to “ethernet_interface”) containing keys - “name”, “next_hop”

Supporting changes needed to files in eos_cli_config_gen :
File: python-avd/pyavd/_eos_cli_config_gen/j2templates/eos/router-service-insertion.j2
File: python-avd/pyavd/_eos_cli_config_gen/j2templates/documentation/router-service-insertion.j2

Which component of AVD is impacted

eos_cli_config_gen

Use case example

Use-case is to support Direct Internet exit configuration on cv-pathfinder wan routers using Port-Channel interface

Post this change , we need some minor work on eos_designs side to generate relevant structured config to facilitate eos_cli_config_gen generate EOS cli.
Specifically
File: python-avd/pyavd/_eos_designs/structured_config/network_services/router_service_insertion.py
Property : router_service_insertion
to add service_connection[“port_channel_interface”] for connection type "port_channel"

Describe the solution you would like

Extend eos_cli_config_gen schema to allow rendering of “port_channel” interface in “router_service_insertion” -> “connections” to generate related EOS cli.
Some additional changes needed on eos_designs side as well

Since this is still not supported on EOS, we will keep this request on hold for now.
