A (hopefully) simple question for someone on here.
When connecting a PE router to a route reflector, there seems to be some form of automatic filtering going on with the bgp.l3vpn.0 table.
On the RR I see the following for a 'show bgp neighbor <pe-address>':
...
Table bgp.l3vpn.0 Bit: 20017
RIB State: BGP restart is complete
RIB State: VPN restart is complete
Send state: in sync
Active prefixes: 9
Received prefixes: 9
Suppressed due to damping: 0
Advertised prefixes: 1156
...
While on the PE, for a 'show bgp neighbor <rr-address>' I get:
...
Table bgp.l3vpn.0
RIB State: BGP restart is complete
RIB State: VPN restart is complete
Send state: not advertising
Active prefixes: 9
Received prefixes: 9
Suppressed due to damping: 0
...
The PE seems to be doing some form of automatic filtering on the received prefixes from the RR, to only include those that are required for routing-instances it has configured.
Is there any command that can override this, and show the full list of prefixes received from the RR?
Thanks
Michael
