  • 1.  Problems Advertising VRF loop back interface to other PE.

    Posted 05-20-2012 13:32
    Hi there, I'm trying to lab a basic Mpls setup with 3 branch srx. Pe----p---pe I am running ldp & ospf between the pe & P routers and Ibpg using lo0 between the pe routers. My vrf config is very simple (using a vrf target), and I have a loop back in the vrf. I am trying to advertise the vrf loopback between the pe's. Ldp, ospf and Ibpg is up. Security config disabled, the boxes running in packet mode & mpls enabled. The route for the loopback is seen on the other Pe in both the bgp table and vrf table but is hidden (unusable). I have tried using import & export targets and rib groups to advertise the vrf loopback, but cannot get the route seen. Any ideas? many thanks!

    Could you provide some shows?, maybe you route is hidden because you cant reach the next  hop.

    Hi Alex, Thanks for the reply, yes that's exactly the problem, I'll post the outputs when I'm in the office tomorrow but I'm trying to figure out a way to either get the vrf loopback into inet0 and make the next hop reachable like that or tweak it some other way. Any thoughts? Thanks, Marc
