Description (partial)

Symptom: In a closed REP ring topology, where the uplink is VPLS using ES40 
card, if one of the REP ports is Open and the other is Alt, then the 
convergence time is high when the Open port goes down.

Conditions: The issue is only seen when the Alt port also resides on the same 
switch where there is a failure, and also if the Uplink happens to be VPLS.
