Hello,
I am trying to learn about MP-BGP and the example configurations I find on the net are not working in my dynamips lab.
I have two routers (EAST and WEST) connected via their fa0/0 interfaces with 10.0.9.0/30 subnet between them.

I am expecting on both routers to see these prefixes in the VRFs that are tied to the loopbacks
What am I missing?

Hello,
the exchange of VPNv4 routes requires the configuration of address-family vpnv4 you have to replicate the configuration for address-family ipv4 under family vpnv4
the key commands are neigh activate and neigh send-community extended to be given under af
Hope to help

Hi
You have not configured "address-family vpnv4" under bgp
Thanks
