Symptom: Node-protection is not working as expected with MoFRR + Multicast multipath, we have seen a situation where for one multicast group the Active and Backup path point to the same upstream device while we have ECMP with more than one upstream device. Conditions: The IOS-XR edge device is configured with MoFRR, Multicast Multipath and command "isis route source first-hop" as per CSCuq69280 ECMP linked to more than one device. The problem was triggered with PIM restart.
