Take a look and see if you have an MPLS tag for the other side's loopback (or vice-versa). You likely need to have LDP running on your link with the other AS in order to make multihop work. With directly connected links, you don't need LDP because each side is responsible for their own reachability. HTH,

R1 ---- R2 ---- R3 ---- R4 R2 and R3 are configured for Inter AS. MPBGP need to be configured on loopback instead of Directlty connected interface. I have configured the same and use the Next hop self inside the AS. It's not working for me. As soon as i change the neighbour to directly connected interface everthing works. Please let me know if anyone has done the same.
