OK I just figured it out. I had to ENABLE inverse-arp on the hub. The hub
did not have any maps (intentionally). I either had to have inverse-arp
enabled or use maps. Why did that stope me from statically mapping on the
spoke? And why I kept seeing the dynamic map? That I'm not really sure!

Thanks for all your private responses

I believe you need to place a 'no frame-relay inverse-arp' on router on the
other end of the circuit. The other router is still broadcasting this
information.

Hi

I know this topic may have been beaten to death but I would appreciate it if
someone can give me any tips for dealing with this. I fully-meshed the F/R
switch. But I disabled inverse-arp on all my interfaces. Why do I still see
this dynamic mapping for DLCI 302 below???? What could be the reason? I
reload the IOS on the router, but it didn't help! I understand if the PVC is
active because there's no way around that, but why is it MAPPED?!!!

Thanks
Tarek
