Configuring Dual-Device IGMP Snooping Hot Backup in a Master/Backup E-Trunk Scenario
To enable the master device to back up IGMP snooping entries to the backup device in a master/backup E-Trunk scenario, configure dual-device IGMP snooping hot backup. After dual-device IGMP snooping hot backup is configured, multicast services are not interrupted during a master/backup E-Trunk switchover.
Pre-configuration Tasks
Before configuring dual-device IGMP snooping hot backup in a master/backup E-Trunk scenario, complete the following tasks:
- Assign IP addresses to loopback interfaces on the master and backup devices, and configure a routing protocol.
- Configure an Eth-Trunk on each device, and add an Ethernet interface to the Eth-Trunk.
- Establishing a Dual-Device Backup Platform
This section describes how to establish a dual-device backup platform to back up IGMP snooping entries. If a network node or link fails, a rapid Layer 2 multicast service switchover is triggered, improving service reliability. - 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. - Verifying the Configuration of Dual-Device IGMP Snooping Hot Backup in a Master/Backup E-Trunk Scenario
After configuring dual-device IGMP snooping hot backup, verify the configurations.
