That is weird.  I've never seen it happen before, I would bet it's a 12.1
thing.

Stephen,
                Yep, that's exactly that happened.  Here's the important
config stuff...

Here's the layout..

I've got the typical hub and spoke topology frame cloud. I've got all 4
devices
using physical and using Inverse-Arp to dynamically activate the PVC's.
here's the
pertinent configs.....  I ran through this a couple more times with the same
result...in some
instances it took a while but Inverse-Arp eventually worked.

HUB router...running 12.1.4 code..

interface Serial1
 ip address 172.16.10.1 255.255.255.0
 encapsulation frame-relay IETF

r2_01#sh frame map

              broadcast,

Serial1 (up): ip 172.16.10.3 dlci 301(0x12D,0x48D0), dynamic,

Anyone got any IOS bug reports on this one...?

Nigel.
