Configuring Multicast Dual-Device Hot Backup

Configuring multicast dual-device hot backup improves multicast service reliability.

Context

Only the NetEngine 8000 F1A supports Multicast Dual-Device Hot Backup.

Pre-configuration Tasks

Before configuring multicast dual-device hot backup, establish a multi-device backup platform.

Enabling a Multicast RBS

An RBS can be enabled to back up multicast services.

(Optional) Configuring IGMP Message Replication

By default, the IGMP message replication function is enabled. When a DHCP STB is dual-homed to master and backup routers, IGMP message replication can be disabled to reduce resource consumption.

Verifying the Configuration

After configuring multicast dual-device hot backup, verify the configuration.
