Hi, I've been trying to get OpenOSPFd working on OpenBSD 4.8 using an GRE over IPsec approach. The GRE tunnel is working for unicast IPv4 packets. I've seen that there are reject routes for 224.0.0.0/4 in the default configuration and set multicast_host to yes which adds the route to the default interface (vr1 in my case). Adding this route to the gre0 device either manually or with the multicast_host key fails. As I just installed OpenBSD a few days ago I'm clueless about how to proceed.
What is the proper way to enable multicast on gre devices? Additionally, if I understand the configuration correctly multicast is only supported on one device simultaneously (can't really believe that). How would I then use OSPF on one interface and an IPv6 router advertisement demon on another? I apologize if these questions seem rather basic and/or if solutions are provided in the documentation (coming from the Linux world I have to say OpenBSDs man pages are even more marvellous than sliced bread).
