I was confused for a sec. You want 102 and 201 to be mapped dynamically and
remove all the other dynamibc mappings. I guess I'd reboot like these guys
said. I've noticed that inverse-arp doesn't always work the way I think it
should ie dynamic mappings will show up until you do a clear frame
inverse-arp even though you did a no frame inverse-dlci on that mapping.

Hi John
nothing in the docs indicate that :: frame-relay interface-dlci <nnn>
disables inverse arp on the interface. Furthermore if you "show
frame-relay map" the you still see a dynamic mapping.
Other than for applying ppp; a specific class to a pvc and bootp
protocol stuff etc ...
I'm not quite sure what this command does in relation to the DLCI when
applied to a primary interface?
Any thoughts
Mick

Mick,
I have a question for you. If you disable inverse arp how will the
Frame process know which dlci's are mapped to an ip address?
