Eric,
Well in the example I'm working on there's 3 routers on the same
ethenrnet segment. I'm trying if possible to keep them all on the same
broadcast segment. This would mean I would have to stand-up 2 tunnels on
each device to support what I'm trying to do. This seems to be quickly
becoming a configuration nightmare...Exactly how much ISIS is on the lab..
:-)
It's worth a try...
Nigel..
