Enabling IGMP NSR
About IGMP NSR
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.
