5.2.1.BASE

Description (partial)

Symptom:
Traffic loss or fib_mgr crash

RIB can in some cases lose its NHID mappings, resulting in a new RIB process downloading mappings conflicting with existing NHID mappings programmed in FIB by a previous RIB process. Platform independent FIB lacks the mechanism to look into NHID collision detection and handling.
