I can see the rationale of saying that a /30 network can run with OSPF interfaces in ptp mode since there are only 2 hosts on it. That said, I *believe* the Cisco routers defaults to broadcast mode for a /30 which would cause some interop issues with the default settings. I don't know the default values for other vendors.
Is it possible to change the autodetect using a function in the bird configuration file? E.g. if the prefix length of the interface is 31 or 32 then use ptp mode else use broadcast mode.
No, you would have to edit the source code (function ospf_iface_classify_() in proto/ospf/iface.c). -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
