RE: Come on No solution from three days now BGP ???

If you have two routes. One reachable and the other not then you are having
problems with your label switch path. Check to make sure the labels are
fully functional in the P cloud. Turn on a debug ip packet with an
access-list at the remote end. See if the traffic is getting to it and if
it responds.
