Im sorry I did not read your entire e-mail before I shot that last one
off. One wa you could do this would be to give each interface an an
assigned-dlci via frame-relay interface-dlci then specify clockrate on
one side and turn off inverse arp don't configure lmi and disable the
interface keepalives with the no keepalive command.

Thanks for the quick reply! I would be satisfied with that and it is
usually how it is setup. But the question specifically stated that "you
need to clear any unused pvc's" I got a clarification on this and you
should not see any other pvc's when you do a show frame pvc. I guess
the one way you could do that is to build a static pvc with no lmi or
keepalive and then it shouldn't receive any pvc's but I couldn't get
that to work. What do you guys think, or do you know how to build it
without lmi?

Thanks,

Jason --
If in the show frame-relay map shows only the statically assigned PVC's
then you are answering the question. If there are more than just the
statically assigned PVC's you need to disable inverse-arp and optionally
no frame-relay arp.

The show frame-relay pvc will always show all the PVC's assigned to that
circuit. As long as they aren't used and don't show in the Frame-Relay
Map output then you are fine.

Subject: Frame-Relay Unused DLCI's

I have been racking my brain over here trying to figure out how to get a
router that learns multiple PVC's from a switch to ignore any but the
statically assigned PVC on the interface. When you do a show
frame-relay pvc it shows the one active PVC but will also show the
unused ones. The reason I ask is that I have a test question here that
asks to clear any unused pvc's from the switch. Does anyone know how to
accomplish this?

The one way I was able to delete the DLCI's was via no frame-relay
interface-dlci 102 command but then the keepalive pops it back in there.
I take away the keepalive and then the circuit doesn't work. Does
anyone know how to accomplish this?
