Hi,
I'm trying to setup OSPF on a working Wireguard VPN using 6.8 amd64
machines. This is what I get:
# ospfd -dvvv
id = "172.26.1.1"
startup
kr_init: priority filter enabled
orig_rtr_lsa: area 0.0.0.0
orig_rtr_lsa: stub net, interface wg0
if_fsm: event UP resulted in action START and changing state for
interface wg0 from DOWN to P2P
send_packet: error sending packet to 224.0.0.5 on interface wg0: Network
is unreachable
send_hello: Network is unreachable
[...]
# ifconfig wg0
wg0: flags=80c3<UP,BROADCAST,RUNNING,NOARP,MULTICAST> mtu 1420

inet 172.26.1.1 netmask 0xffffff00 broadcast 172.26.1.255
Is it possible to use a wg(4) interface for ospfd(8)?
Thank you,
Best.
Hello.
It is possible, I use it myself. You have to allow multicast address on
wg(4) interface(s):
225.0.0.5 for all OSPF routers
224.0.0.6 for all DR/BDR
(I use wgaip 0.0.0.0/0, so my config is not relavant for you)
Regards,
