Description (partial)

Symptoms: The extranet receiver retains RPF pointing to a nonexistent source
MVRF, which can lead to a crash.
Conditions: This symptom is observed when PIM is disabled on the source RPF
interface or RPF on the source MVRF mroute changes to NULL (that is,
unreachable) under the extranet scenario. If mroute is cleared in the source
MVRF, it will lead to a crash.
