Description (partial)

Symptom:
With 7600 as dual homing for source and RP at a remote CE, then on switchover from Nominal to backup, duplicate packets are seen at the remote CE.
Note: Nominal PE also has local recievers.

This happens because the Nominal PE keeps sending the packet back to the core via deafult MDT. This should not happen and hence the issue.

Conditions:
This issue has got exposed from CSCue61691. So issue is applicable only to the releases where CSCue61691 is committed.
