Hi Cedric,As far as I know, wireguard doesn't support multicasts yet, which OSPF uses for neighbor discovery. The reason why BGP works is because it uses unicast TCP packets as means of communication.To get around this, try telling BIRD that your wireguard interface is an NBMA network (or a point-to-point link).vistaOn Mon, 16 Apr 2018, 11:27 cedric Kienzler, <cedrickienzler1@gmail.com> wrote:_______________________________________________CediBest regards,Thanks a lot.Anyone here that could help me?Interesting fact: BGB using Bird works just fine.Should i configure multicast IPv6 (fe80::) on the interface too to get OSPF working?For IPv6 i use 2a03.... as prefix.I use both, IPv4 and IPv6 and everything works fine. I can ping through the tunnel, traffic flows perfectly, but when i try to configure OSPF using the Bird routing daemon, i didn't even see a HELLO message. Also when trying to list the interface using 'show ospf interfaces' i didn't even see the Interface.Hey List,i'm currently facing issues with OSPF over the wireguard tunnel.
