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: Jun 23 15:34:14 dcg-1 bird6: ospf1: Socket error on bnx0: Invalid argument Jun 23 15:34:24 dcg-1 last message repeated 6 times Jun 23 15:34:24 dcg-1 bird6: ospf1: Socket error on bnx2: Invalid argument Jun 23 15:34:24 dcg-1 bird6: ospf1: Socket error on bnx0: Invalid argument Jun 23 15:34:28 dcg-1 last message repeated 3 times this is my config: [root@dcg-1 ~]# cat /etc/bird6.conf log syslog all; router id 94.142.247.1; protocol kernel { scan time 20; export all; } protocol device { scan time 2; } protocol direct { interface "lo1"; interface "bnx0"; interface "bnx2"; } protocol static { route 2a02:898::/32 blackhole; } filter only_loopbacks { if net ~ [ 2a02:898:0:300:0:0:0:0/64{128,128} ] then accept; reject; } protocol ospf ospf1 { tick 2; rfc1583compat yes; import filter only_loopbacks; export filter only_loopbacks; area 0.0.0.0 { interface "bnx0", "bnx2" { hello 10; retransmit 2; wait 10; dead 40; type pointopoint; }; }; } [root@dcg-1 ~]# birdc6 show ospf nei BIRD 1.4.3 ready. ospf1: Router ID Pri State DTime Interface Router IP 195.85.225.5 128 exstart/ptp 00:34 bnx0 fe80::21f:12ff:fe1c:3482 Kind regards, Job
