Can anyone tell me how I could see all the prefixes imported/exported by particular RT? Is there any command which will show me which prefixes are imported into the VRF as a result of 1 of the many configured RTs for that VRF?
you can define an extended community list and match on that. Example:
R1(config)#ip extcommunity-list expanded myRTlist permit 65000:1
R1#show bgp vpnv4 unicast [all|rd RD| vrf VRFNAME] extcommunity-list myRTlist
R1#show ip bgp vpnv4 all extcommunity-list myRTlist
This will filter based on RT, which is especially helpful on route-reflectors, where no VRFs are configured.
Hope this helps!
