This can be achieved with bgp_defaults

Add the command directly under this hood. Meanwhile I will add the feature.

Thanks!

Yes! I do that today to render the config, and it works great! The reason a key is valuable is that I don't have to walk the list to understand the intent of the configuration when trying to validate the configs.

Note that implementing this would need to add some modification in some of the BGP overlay logic where we explicitly disable some peer-groups in ipv4 address family which will be useless with this turned on.

This issue is stale because it has been open 90 days with no activity. The issue will be reviewed by a maintainer and may be closed

Closing this request because this is achieved through bgp_defaults key.

Will be addressed by https://github.com/aristanetworks/ansible-avd/pull/2799
