Todd,
Seriously what version of IOS and what model of
routers.
When this happens to me, if it happens to me (which it
rarely does as I make it a rule to shut the interface
before enabling frame-relay encapsulation - however I
realize how this happens and that it could be present
in any given lab), what I do is:
1. clear fram inarp - ought to work but I never trust
it.
2. shut down the interface with two commands prominent
under the interface:
encap fram
no fram inv
3. reload the router
4. no shut the interface and then...
5. sh fram map
Are they gone yet...
Now we could just as easily change the encapsulation
and change it back.
But if we did and the int was not down - ooops they
would be back again.
Let me know if you are doing this and it is still
happening.
However it helps to remember what the technology is
doing whenever inverse arp is being performed.
And a good debug command may be in order:
debug frame packet - ought to do the trick.
What is the output - turn it on as you are completing
each step.
And if you have more interfaces with frame-relay
enabled get a little more specific.
debug interfaces s0/0/0
and then debug fram packet.
That should do it...
What are you seeing...
Might be weird, but help us out a bit.
