This feature backs up information about IGMP interfaces and IGMP multicast groups to the standby
process. The device recovers the information without cooperation of other devices when an
active/standby switchover occurs. Use this feature to prevent an active/standby switchover from
affecting the multicast service.
To enable IGMP NSR:
Step
1. Enter system view.
2. Enable IGMP NSR.

The reset igmp group command might cause multicast data transmission failures.
