I would like to filter bgp route update tagged specific community-list from neighbor bgp router.
for example, A router bgp update like below
184.108.40.206/24 set community 100:10
220.127.116.11/24 set community 100:20
B router doesn't update 100:20, but accept 100:10 route, Is it possible?
How can I configure on B Router?
The point of my question is that B router doesn't update specific community-tagged route, when updating route from A
You can filter an update from A to B with a simple route-map matching a community-list. The route-map below will only permit routes in with the community 100:10 set.
ip community-list 1 permit 100:10
route-map Filter-A permit 10
match community 1
router bgp 1
neighbor A.A.A.A route-map Filter-A in
