I have seen this problem before with frame. LMI being local to the frame switch means the interface does not go down and backups routes do not kick in. One way to overcome this is to monitor layer 2 by using the “frame-relay end-to-end keepalive mode bidirectional” command within a map class on both sides. This command sends a keepalive every 15 seconds, if 3 are missed the interface will change to down/down even though the interface is receiving LMI from the frame switch. I hope this helps.
