I am not sure if i understand your scenario, but if you run both TUN/TAP
endpoints on one machine, i would be surprised if OS network code wouldn't
be confused by that. If not, you should try ping and try to run OSPF
in NBMA mode (which will use just unicasts).

Generally, it works over OpenVPN tunnels, which use TUN/TAP devices,
but in that cases both endpoints are on different machines.
