Symptoms: Traffic drop of MVPNv6 data MDT packets is seen.

Conditions: This symptom is observed on doing a VRF delete and adding it on the
encapsulated PE in a scaled MVPNv6 setup; the L3 DENY RESULT drop counters
increment for the encapsulated VLAN v4.
From a multicast point of view, the drop is at the point where the packet
reaches the encapsulated VLAN v4 to proceed further with backbone forwarding.
