(Optional) Enabling the Backup in a VRRP Group to Forward Traffic


Only the S5720HI supports this function.

On large aggregation networks of enterprises, terminal users use active and standby links to access aggregation devices that have a VRRP group deployed. The aggregation device connects to the active link is the master device, and that connects to the standby link is the backup device. If the active link or the master device fails, a link switchover occurs. However, the master/backup switchover in the VRRP group has not yet completed. Therefore, a traffic interruption occurs and lasts for a short period.

To prevent traffic interruptions in such scenarios, enable the backup device in a VRRP group to forward traffic. This configuration ensures carrier-class reliability.

Figure 4-12  Configuring the backup in a VRRP group to forward traffic


  1. Run:


    The system view is displayed.

  2. Run:

    interface interface-type interface-number.subinterface-number

    The view of the sub-interface on which a VRRP group is configured is displayed.

  3. Run:

    vrrp vrid virtual-router-id backup-forward

    The backup in the VRRP group is enabled to forward traffic.

    By default, the backup in a VRRP group is disabled from forwarding traffic.
