Usage Scenario

To implement dual-device user service hot backup, run the service-type command in the RBP view to enable remote backup for user services.

Prerequisites

An RBP has been created using the remote-backup-profile file-name command.

Precautions

To ensure that the user service information on the master device can be completely backed up to the backup device during a master/backup VRRP switchover, run the vrrp vrid virtual-router-id preempt-mode timer delay delay-value command to set a preemption delay greater than or equal to 600 seconds for the VRRP group.
The service-type dhcp-server parameter can be used to enable remote backup for the DHCP server only after VRRP is used to determine the master/backup status in dual-device hot backup.
To ensure that the user service information on the master device can be completely backed up to the backup device during a master/backup VRRP switchover, run the vrrp/vrrp6 vrid virtual-router-id preempt-mode timer delay delay-value command to set a preemption delay greater than or equal to 1800 seconds for the VRRP group.
The service-type dhcpv6-relay parameter can be used to enable remote backup for the DHCPv6 Relay PD routes only after VRRP is used to determine the master/backup status in dual-device hot backup.
