Hello David
Yes, you are correct. I’ve verified this myself as well. One of the requirements, as stated in this Cisco documentation is that:
All members of a peer group must share identical outbound announcement policies (such as distribute-list, filter-list, and route-map), except for default-originate, which is handled on a per-peer basis even for peer group members.
Also note that:
You can customize the inbound update policy for any member of a peer group.
Thanks for noting this. I will make a NetworkLessons note on the topic and link to it here when I have done so.
Indeed BGP peer templates are a more flexible and powerful tool that you can use if you want to achieve what you are describing.
Thanks again!
