does anybody know if the following is possible.........
1. I have server X (just a made up name) with an iBGP session to a Cisco router.
2. Server X announces routes to the router with no-advertise and no-export communities set - the router enforces this with an inbound route-map.
3. The router has an iBGP session with a route log server as well a many other iBGP sessions to other routers.
Q. When the router receives a route with the communities set as in 2 from server X, is it possible to make the router advertise this route only to the route log server (for route audit purposes) but to honour the no-advertise community for all other iBGP peerings?
It is not possible to make the server iBGP peer directly with the route log server because the server X cannot be trusted.
Ideally, I don't want to be putting lots of outbound filters on all of the routers iBGP peerings.
Thanks for your time!
