Hello, I run OSPFv2 between multiple Linux hosts over wireguard tunnels between them in a full mesh. This works fine in Ubuntu Linux 20.04, but if I try to add a FreeBSD 12.2-RELEASE-p1 host, I receive the following error: bird[9767]: ospf1: Socket error on wg-lon1: Network is unreachable Could this be related to changes in FreeBSD 12, like FreeBSD 11 e.g., https://github.com/BIRD/bird/pull/1? Thanks for any advice you can give me. Best, Adam BIRD and Wireguard are built from FreeBSD ports. $ bird --version BIRD version 2.0.7 $ wg --version wireguard-tools v1.0.20200827 - https://git.zx2c4.com/wireguard-tools/ $ uname -a FreeBSD <hostname> 12.2-RELEASE-p1 FreeBSD 12.2-RELEASE-p1 GENERIC amd64 wg0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1420 options=80000<LINKSTATE> inet 10.1.5.5 --> 10.1.5.5 netmask 0xfffffff8 groups: tun nd6 options=101<PERFORMNUD,NO_DAD> Opened by PID 9459 $ netstat -rn [...] 10.1.5.1 wg-lon1 UHS wg-lon1 10.1.5.5 link#5 UH wg-lon1 [...] $ cat /etc/bird/bird.conf [...] protocol ospf { ipv4{ import all; export all; }; graceful restart on; area 0 { interface "wg0" { type nbma; authentication none; neighbors { 10.1.5.1 eligible; }; }; }; } [...]
