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 ?

                multiplier 5;

        };

        neighbor xx.xx.xx.xx local yy.yy.yy.yy;

       neighbor h.i.j.k local o.p.q.r;

       neighbor s.t.a.b local  u.w.u.j;

}
