I am having some difficulty getting my OSPF configuration to play nicely with OpenVPN tunnels on FreeBSD. I have a number of point-to-point tunnels between sites, with a BIRD instance running on each tunnel endpoint. Endpoint addresses for a tunnel use a logical /31. Initially, the BIRD instances would talk to each other, but the endpoint addresses were not advertised by OSPF, making them unreachable. I remedied this by adding stubnet declarations (/32) for each of the tunnel endpoints. This has the effect of making all of my endpoint addresses reachable, but causes another issue. In this configuration, if I restart one of my OpenVPN tunnels, it fails to set addressing on the tunnel, because the host route already exists in the routing table (due to the stubnet). I have attached my OSPF configuration below. Is there some better way of configuring this, to make my tunnel endpoints advertise properly without declaring them as stubnets? Thanks! protocol ospf { tick 2; area 0 { stub no; stubnet 10.70.0.3/32; stubnet 172.26.26.5/32; stubnet 1.2.3.221/32; interface "re0" { stub; cost 100; hello 2; dead 10; authentication cryptographic; password "password"; }; interface "tun*" { type ptp; hello 2; dead 10; authentication cryptographic; password "password"; }; }; }
