6.2(5.65)S3

Description (partial)

Symptom:
On a VPC+ testbed when ISIS adjacencies are cleared from one of the peer switches, traffic loss is observed.

Conditions:
On the core switches connected to the peer, there is delay in programming of DELETE route transactions, as a result of which ADD precedes DELETE of switch routes from M2RIB to U2RIB. This results in traffic outage.
