HI Mark Thanks a lot for your response..I have everything working fine withLDP without any issues..I just wanted to deploy RSVP-TE for fasterfailover in the backbone..And there I got stuck up with the full-meshof TE among PEs or using Broken Static LSPs between PE-P and P-PE.. Thanks for sharing the rib-import methodology to get rid of staticroutes for inet.3 resolution for BGP-Next Hops.. Just a clarification on the "ldp-tunneling" part..Do I need to applythis at all the PE/P routers to run LDP over broken LSPs between PEs..Is there a provision in Junos without using LDP Tunneling to passtraffic between PEs when using broken LSPs ?
