Hi Divin

Thanks a lot for your explanation.

I Just starting to learn MPLS. It happens to be related to my work, so I
have to learn MPLS.

So, now I clearly know this is happen in MPLS Environment. Thanks a lot for
that.

Mark

I think when u use VRFs the PE router automatically changes the NEXT-HOP to
itself. because the CE router has no idea of the PE --P --P Connections.! it
only knows abt the interface in its VRF . The vrf interface.

Are these VPNv4 or IPV4 sessions, then? Are you sure that "next-hop
self" is not set for the VPNv4 AFI?

I'll also second request for relevant configs and "show ip bgp"
outputs (if it's VPNv4, then do show for relevant CRF and "vpnv4
all")...
