Traffic via tunnel not working as MP-BGP routing updates not learned on RR Server.

[arora_ayesha]

Hello,

Please help me with this problem. Attached network diagram & router's configuration for ref.

Requirement,

To route the traffic from R1 to R3 via RSVP-Tunnel inside VRF "a"

Issues:

1.MP-BGP routes not being exchanged between the router's. However the i-BGP neighbors through RR are UP.

2.How will the traffic from R1 to R3 via RSVP-Tunnel can move into VRF "a"

Thanks for reviewing the configuration and I will be grateful to get the reply.

Regards,

Ayesha

Hello Ayesha,

on R2 in address-family vpnv4 you need to enter again the neighbor ... route-reflector-client command for the two PE nodes.

This is an expected behavior as IOS allows reflection of routing updates in a selective way.

This should fix the MP BGP routing exchange

In real world oftern RRS for VPNv4 are different devices then those used for the ipv4 unicast default address family. This is an advantage for achieving better scalability in the control plane.

Also R2 doesn't need at all to have a VRF a configured on it, route reflection does not require VRF membership to work. Also this is a scalability advantage.

Hope to help

Giuseppe
