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

A remote backup profile (RBP) is created, and the RBP view is displayed.
Remote backup is enabled for IGMP snooping services.
Return to the system view.
The Eth-Trunk interface view is displayed.
The RBP is bound to the Eth-Trunk interface.
The configuration is committed.
