Yugandhar, the last few posts were just what I was noting earlier: You have 
to learn the commands to allow you to walk across your network step by step 
to see which tables are getting populated and which are not. You also need 
to understand the difference between a global routing table and a vrf 
table. The command Robert put below is looking at the vrf information 
relative to what MP-BGP knows, and it is showing what MP-BGP knows on the 
BGP and core side of the PE router. The show ip vrf command shows what the 
vrf  knows on the CE side of the PE. If the route you seek is in one and 
not the other in the same PE, then you have to think about how the route 
gets moved from one to the other, and what is not happening: redistribution 
issues, address-family misconfiguration or the like. Step by step....CE1, 
PE1 vrf, PE1 bgp vpnv4, then to the other side PE2 bgp vpnv4, then PE2 vrf, 
and on to CE2 etc.
