Unnumbered and tunnel interfaces in OSPFv3

[Nic Neate <Nic.Neate at DATACONNECTION.COM>]

Hi all,

I have a few OSPFv3 questions I was hoping someone could help me with.

1.  Is there any concept of an unnumbered interface in OSPFv3?  (As far as I
can see from RFC 2740, there isn't.)

2.  If yes, how do they work?  I would guess most principles from OSPFv2 can
be carried over, but what about usage of the Link-LSA?

3.  If not, are there any guidelines on how, for example, RSVP tunnel
interfaces should be handled?

Thanks in advance,

Nic
