RE: ISIS over frame-relay troubles.....
What you need to do is use tunnels with frame relay to fix this. You have the cause exactly right too. There is no equivalent to the ip ospf network command.

Re: ISIS over frame-relay troubles.....
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..

Re: ISIS over frame-relay troubles.....
I would be surprised if the lab said you must using a "multipoint interface" and not a point-to-point. Especially since ISIS is not support with this type of interface. Now it could say do ISIS using maybe using "multipoint interface" which ever method that will work. The suggestion I guess of doing a tunnel seems like the only way with this type of interface.
