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).

Hey List,

i'm currently facing issues with OSPF over the wireguard tunnel.

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.

For IPv6 i use 2a03.... as prefix.

Should i configure multicast IPv6 (fe80::) on the interface too to get OSPF working?

Interesting fact: BGB using Bird works just fine.

Anyone here that could help me?

Thanks a lot.

Best regards,

Cedi

I have something like this (but with frr/quagga)

router ospf
ospf router-id 172.16.223.2
network 192.168.123.0/24 area 1
network 172.16.223.0/24 area 1

172.16.223.2 being the wg0 local interface
