Task is set up LSP form r3 to t7 and provide protection for LSP without using secondary LSP.

I followed the configs in the book. LSP doesn't come up if have 10.0.3.4 path configured for this LSP. It does come up if i remove the specific path. Here are my config..i can't really figure out why it's failing.

    Any more debugs... mpls lsp extensive outputs? rsvp outputs
    IS-IS Sleeps.
    BGP peers are quiet.
    Something must be wrong.

    also what's the reason that loop backs are not advertised in OSPF?i don't see any other way to bring up iBGP
  • hoogen82hoogen82 Member Posts: 272
    How about adding no-cspf to your lsp statements.. I do think r3 and r7 maybe in different areas? There is some funky behavior on this one... for the question you ask regarding why it works if you remove the specific route...

    I do not understand your next question ... Loopbacks not advertised into ospf?
    IS-IS Sleeps.
    BGP peers are quiet.
    Something must be wrong.

    i misread the notes (under the ospf topology diagram in beginning of the case study) where it says loopbacks are not assigned to any specific area..

    i do know that loop backs are auto advertised

    i'll test the no-cspf..i think that'll work..
