I have a Frame connection between two sites, A and B. If the router crashes at B, wouldn't A still see the DLCI for B? Is there any scenario where this wouldn't be the case? If B gets blown off the map, shouldnt A's frame interface be in at least an up/down scenario?In theory, when the remote LMI goes down, or any part of the PVC internal to the carrier goes down, the local LMI should go INACTIVE. In practice, this is unreliable at best; for some carriers, you will always get ACTIVE status no matter what.
For a real frame relay (not the frame relay on customer end that terminates into the ATM circuit on your end) if you want the interface to go up/down or down/down when there is a problem on a line, you must configure frame relay using sub-interfaces. Works like a charm. Alex
