[re-sending to the list with the correct From address] Hi,
You should be able to do this with 'topology subnet' on your server end. It doesn't work with net30 (the default) or p2p, but I can confirm that OSPFv2 for IPv4 works in broadcast mode with 'topology subnet'. I think there are issues with IPv6 on tun links with respect to multicast, so you may struggle to get OSPFv3 working, but I haven't had to do that yet.
