Description (partial)

Symptom:
In rare occurrences, the BGP table, RIB and FIB can become out of sync.

Conditions:
In rare occurrences, the BGP table, RIB and FIB can become out of sync.  We see this when learning a large amount of BGP routes (128,000) from many neighbors (32 way to 64 way ECMP) followed by clearing the BGP table.
