fail to establish neighbors #5863

Closed magnate3 closed 4 years ago

magnate3 commented 4 years ago

In my test, the spine fail to establish neighbors with two leaves:

spine : 10.10.18.195/24 leaf1: 10.10.16.82/24 leaf2: 10.10.16.81/24 all of they can ping with each other

  1. my os is as following:

It looks like you BGP session with leaf is trying to come up, at least I can see that they are exchanging keepalive (Openconfim and established state) and then there seems to be terminating signal being sent.

Could you please let me know what are the triggers here? Why are all clients are being terminated?

qlyoung commented 4 years ago

What does this show:

journalctl -xeu frr.service

All the daemons are being terminated, so systemd is killing them, which usually means watchfrr isn't getting liveness pings from daemons. Journalctl should have some more info about what's going on.

Yeah, it's currently the same for me, i can confirm.
