OpenBSD 6.0, ospf6d and the routing table

[BSD4me]

I am running ospfd and ospf6d on OppenBSD 6.0.

When started, ospf6d populates the routing table with routes learned from a neighbor. The problem is those routes disappear from the routing table after a few minutes.

The daemons are still running:

# ps waux|grep ospf
root 66882 0.0 0.0 696 1480 ?? Is 28Jan17 0:02.78 /usr/sbin/ospfd
_ospfd 28885 0.0 0.0 908 1676 ?? Sp 28Jan17 0:11.38 ospfd: ospf engine (ospfd)
_ospfd 50640 0.0 0.0 712 1520 ?? Ip 28Jan17 0:00.59 ospfd: route decision engine (ospfd)
_ospf6d 74055 0.0 0.0 980 1748 ?? S Tue03PM 0:00.38 ospf6d: ospf engine (ospf6d)
_ospf6d 52428 0.0 0.0 728 1532 ?? I Tue03PM 0:00.03 ospf6d: route decision engine (ospf6d)
root 70126 0.0 0.0 724 1480 ?? Is Tue03PM 0:00.09 /usr/sbin/ospf6d -v


The system is still advertising routes to its neighbor.

Nothing (other than startup) is logged. I even started ospf6d with "-d -vvv". After initial load, the output stops and ospf6d keeps running. Once again after a few minutes, the learned ospf IPv6 routes drop from the routing table. No additional output is displayed on the screen when that happens.

ospfd (IPv4) works fine.

ospf6d on an OpenBSD 5.9 system works fine with an identical configuration.

Even though I have rules allowing ospf traffic, I have also tried disabling the firewall (pf).

I see ospf hello's coming in on the interface.

"ospf6ctl sh rib" and "ospf6ctl sh fib" show the learned routes.

# ospf6ctl fib couple
couple request sent. --> Has no effect.

Config is very simple:

router-id 192.168.1.1

area 0.0.0.0 {
interface em0 {
}

interface bnx1 {
passive
}
}

I have searched much, but not found anything.

Any help or advice would be appreciated.

Thanks.
