Hi, My firewall is using bfd and when typing "show bfd session" on it, it shows me down sessions
concerning my ebgp connection, it's a non-multihop connection. here is my bgp configuration : neighbor X.X.X.X remote-as 252 use neighbor-group NG-PE-CE bfd fast-detect bfd multiplier 3 bfd minimum-interval 300 and here is the "show bfd client", (i'm using bfd for my ISIS configuration) Name Node Num sessions --------------- ---------- -------------- MPLS-TE 0/RSP0/CPU 3 bgp-0 0/RSP0/CPU 0 bgp-0 0/RSP1/CPU 0 ipv4_static 0/RSP0/CPU 0 ipv4_static 0/RSP1/CPU 0 isis-IGP-MPLS 0/RSP0/CPU 3 isis-IGP-MPLS 0/RSP1/CPU 0 pim 0/RSP0/CPU 3 pim 0/RSP1/CPU 0 rsvp 0/RSP0/CPU 0 rsvp 0/RSP1/CPU 0 thanks. ----- Message d'origine ---- De : Marc Binderberger <[email protected]> À : Gert Doering <[email protected]> Cc : chams <[email protected]>; [email protected] Envoyé le : Mar 1 février 2011, 13h 42min 16s Objet : Re: [c-nsp] BFD on ASR 9000 Hello Gerd and Chams, > My guess is that your unnamed firewall doesn't do BFD... that is problem #2 ;-) - but it still should show up with "show bfd session" on the ASR9k as a DOWN session. The eBGP session must be non-multihop, i.e. it must be between the addresses of the link ASR9k--FW. I assume this is what you mean with point-to-point? BFD really doesn't know anything about "i" or "e"-BGP. All it requires is a "bfd fast-detect" line under the BGP neighbor. What is "show bfd client" showing?
