* While bird defaults to a "ptp" link type for eth0, bird6 defaults to "broadcast".

* The dummy0 interface defaults to being a stub interface in bird, while it requires configuration in bird6.

That is because OSPFv2 uses IPv4 addresses where /31 signalize ptp link and /32 stub link, OSPFv3 uses IPv6 link-local addresses and there is /64 everywhere.

Good to know, I was mostly pointing it out if anyone was wondering why my configuration differed somewhat between the protocols.

Sorry for bringing up this old thread but I noticed my interface was defaulting to a "ptp" link type when being configured with a /30 prefix which is not mentioned as a special case above. I realize a /30 is a "normal" two-host network with /31 being somewhat of a special case, but I want to make sure this is still expected behaviour for BIRD. -- Patrik Lundin
