Two routers on a point-to-point ethernet, the link between them dropped
out but ports stayed up. The link came back after ~2h or so but ospfd
doesn't recover -
first router:
195.95.187.3 1 FULL/OTHER 00:00:03 195.95.187.16 ix1 1d14h45m
Neighbor 195.95.187.3, interface address 195.95.187.16
Area 0.0.0.0, interface ix1
Neighbor priority is 1, State is FULL, 92 state changes
DR is 195.95.187.16, BDR is 0.0.0.0
Options -|O|-|-|-|-|E|-
Dead timer due in 00:00:03
Uptime 1d14h49m
Database Summary List 0
Link State Request List 0
Link State Retransmission List 0
second router:
195.95.187.1 1 FULL/OTHER 00:00:03 195.95.187.17 vlan730 1d14h45m
Neighbor 195.95.187.1, interface address 195.95.187.17
Area 0.0.0.0, interface vlan730
Neighbor priority is 1, State is FULL, 12 state changes
DR is 195.95.187.17, BDR is 0.0.0.0
Options -|O|-|-|-|-|E|-
Dead timer due in 00:00:03
Uptime 1d14h46m
Database Summary List 0
Link State Request List 0
Link State Retransmission List 1
i.e. they both think that they're DR and that there's no BDR.
(1d14h ago, yeah I was a bit slow spotting it this time..)
Not the first time I've seen it (on various links over various releases)..
In this case they're on a /31 though I've seen it on /30's previously.
Are other people seeing this?
Does anyone have an idea where the bug might be, or a better suggestion
than removing the interfaces from ospfd.conf, reloading, re-adding,
reloading again?
dmesg from one end for completeness, but it's not really relevant.
