Classified as: {Hitachi Rail - Public} I configured 4 bfd sessions like below, but 3 sessions are up, I check many times, those 4 session seems no any difference. I used birdc command to check "birdc show bfd sessions session" only 3 sessions, 1 session not list here. Why I configured, bird not take it. The stranger thing: even I comment out 3 sessions in conf file, just leave one, kill bird daemon, restart bird, Use birdc to check bfd sessions, still same, the 3 sessions are up, It seems bird not read configuration file again. What would the issue be ? # Bidirectional Forwarding Detection (BFD) protocol bfd BFD_CTI { interface "*" { min rx interval 500000 us; min tx interval 500000 us; idle tx interval 1500000 us; multiplier 5; }; neighbor xx.xx.xx.xx local yy.yy.yy.yy; neighbor a.b.c.d local e.h.i.j; neighbor h.i.j.k local o.p.q.r; neighbor s.t.a.b local u.w.u.j; } Chris LIU {Hitachi Rail - Public}
Hello, with this, are you sure that you are actually editing the right config file? If you do a syntax error right at the beginning of the file, just putting garbage there, does it fail? Maria On 2 December 2024 23:11:30 CET, LIU Chris via Bird-users <bird-users@network.cz> wrote:

FWIW on bird1 I would once in a while have to birdc restart the bfd proto to get it to come up on BGP sessions. i.e. /opt/shared/bird/show_bgp_sum v1.07 a10_biznet 65305 E 208.74.83.11 up 2024-11-23 0 BFD Sessions: [birdc "show bfd sessions"] IP address Interface State Since Interval Timeout 208.74.83.11 --- Up 2024-11-23 0.750 protocol bfd { multihop { interval 750 ms; multiplier 5; }; neighbor 208.74.83.11 local 208.74.80.53 multihop; And then bfd yes on that MH session (this is a route server so Im using MH for my bgp sessions) ... + Jon Larsen: CTO Richweb, Inc. + Richweb.com: Providing Internet-Based Business Solutions since 1995 + Business: (804) 368-0421 x 101; Mobile: (804) 747-8592 + GnuPG Public Key: http://jlarsen.richweb.com/jlarsen.gpg
