I have no proper exp. with *bsd but from what I've heard:

* If you want unnumbered interfaces,then do you have a /32 assigned to
loopback?
* Ensure this address used as preferred source address (pref_src(?))
within the kernel protocol
* don't use stub. IIRC, stub means: do not send and do not participate.
* for unnumbered interfaces you want to use broadcast to send your pkts
to the multicast address

I hope I'm not totally off. Have a nice time...
