Description (partial)

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

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.
