Hi Thorsten, I'm not very into BIRD code or OSPF as a protocol but I do know a thing or two about OpenVPN and general networking. According to your sample, it seems BIRD uses the IANA assigned multicast addresses to communicate and (try to) form an OSPF adjacency. Per default, OpenVPN uses the re

Hi, I am trying to use OSPF over an openvpn link. tcpdump tells me that both ends send their HELLO packet but bird does not want to recognize them. When looking at ospf_rc_hook() in proto/ospf/packet.c the HELLO packet arrives in bird, but is discarded because of "strange address combinations

Hello all, I am trying to establish OSPF over OpenVPN without any luck. The client side always turns up with no neighbours. I’ve tried pointtopoint and exclusively listing my neighbours all with no luck. I originally was using the tun interface and switched to tap hoping that would help, but
