Re: bird 1.4.3 ospfv3 issue on openbsd

25 Jun 2014

      Hi all,

I've upgraded up and down to see when the issue was introduced: between
1.4.0 and 1.4.1. 

Ondrej, Martin, how can I help debug this? Would you like access to the
machines?

Kind regards,

Job

Hi all,
I just upgraded from 1.4.0 to 1.4.3 (compiled from -current ports) on OpenBSD
5.5, now OSPFv3 adjecencies don't establish any longer, they remain stuck in
exstart. I saw a thread a while ago about IPv6 issues on FreeBSD with 1.4.1,
maybe this is related but the bug fix does not work on OpenBSD?
syslog is filled with these messages:
