It's very interesting that you mention this today. I'd never,
ever, seen anyone use the frame-relay interface-dlci command on
multipoint interfaces until last night when another list member
who shall remain nameless (Tim Ouellette) called me about this
exact issue.
We had a hub router configured with a multipoint subinterface
using two frame-relay interface-dlci commands instead of frame
maps. At first I thought this wouldn't work at all but it did,
somewhat. The command reference says appears to say that it
ought to work in conjunction with inverse ARP.
However, it didn't seem to be stable and behaved erratically.
When we removed those two statements and replaced them with two
frame maps things settled down quite nicely.
Specifically, we were having issues with EIGRP. It seemed to
work, but the output of show ip eigrp neighbors indicated that
things might not be working as they ought to be. Sorry, I
don't have that info available here at work but if Tim reads
this might be able to post the exact results.
I've always been under the impression that we only used the
frame-relay interface-dlci command on point-to-point
subinterfaces so I've always used frame maps in all other cases.
What do you all think about this issue? Is there a time to use
one or the other on multipoint interfaces? Any gotchas we need
to look out for?
Thanks,
John
