Przemyslaw,
The OSPF RID doesn't need to be in the remote router's table for the
virtual link to come up. It's used for identification, I believe. Think of
the virtual link as a tunnel between the two 'connecting' interfaces. Once
you enter the RID for the virtual link, OSPF will find that RID in it's
database and look up the best path to it. I think that's how it works...

Subject: OSPF virtual links
Group,
Simple question:
Is it possible to create virtual link (connect virtual areas)
using interface address instead of OSPF router ID?
Cisco documentation says:
area <area-id> virtual-link <router-id>
Obviously, using RID is better for stability reasons,
but one can imagine hyphothetical situation when OSPF RID
is not in routing table, so it would not be reachable for
virtual-link.
Comments?
Thanks,
Przemek
