Description (partial)

Symptom: ME-6524 was configured for NAT feature.  When one of the primary link is failed on this device, even though the next-hop-information is updated by the BGP, NAT traffic continues to drop for few minutes.  NAT translation happens after say 3 - 4 minutes.  End-end traffic then continues as normal.

Conditions:  This happens when a link failure/node failure/sw crash event happens in the network
