This section describes how to enable remote backup for IGMP to implement IGMP entry consistency between the master and backup devices.
In a master/backup E-Trunk scenario, IGMP dual-device hot backup enables IGMP entry backup between the master and backup devices through a remote backup service (RBS) channel, ensuring multicast service continuity. To enable IGMP dual-device hot backup to take effect, you must enable remote backup for IGMP.
