If I understand it right, you are trying to ping the interfaces on PE2 that are within different VRFs from PE2 itself? If that is the case, you should be using 'ping vrf BANK1 ip-address'

Subject: [MPLS-OPS]: problem in implementing the BGP MPLS VPN

Hi all

 

I have a problem in implementing the BGP MPLS VPN setup. Here Iam giving the network diagram and configuration of one PE router. Iam unnable ping to the own interfaces of PE2 but I can ping interfaces of PE from the CE routers........means as shown in the network diagram I can ping PE2-------- F0/0 & F0/1   from the CE1(Bank1) and CE2(Bank2),but from PE2 I can't ping its own interfaces. RIP is enabled on all CE-PE links.
