Enabling Remote Backup for IGMP Snooping Services
This section describes how to enable remote backup for IGMP snooping services to implement IGMP snooping entry consistency on the master and backup devices.
Context
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.
Procedure
- Run system-view
The system view is displayed.
- Run remote-backup-profile profile-name
A remote backup profile (RBP) is created, and the RBP view is displayed.
- Run service-type igmp-snooping
Remote backup is enabled for IGMP snooping services.
- Run quit
Return to the system view.
- Run interface eth-trunk trunk-id
The Eth-Trunk interface view is displayed.
- Run remote-backup-profile profile-name
The RBP is bound to the Eth-Trunk interface.
- Run commit
The configuration is committed.
