Description (partial)

Crash of the mrib process on RSP in ASR9k nV Edge Cluster system

Crash of the mrib process is seen on the RSP when an ASR9k system is setup as a nV Edge Cluster and certain triggers are performed. This issue occurs when state of the core facing interfaces and inter-rack link interfaces are changed at the same time. The trigger could be any of the following:

1) Reload of LC which has both core facing and inter-rack link interfaces
2) Reload of primary or remote rack (this will cause both core facing and inter-rack link interfaces to go down at the same time)
3) Removing core facing and inter-rack link interfaces together via configuration change (such as commit replace or rollback)

A single crash is seen after which the system recovers.
