Configuration Task Summary

Configuration Task Summary

After basic VRRP functions are configured, VRRP can work properly. To deploy special VRRP functions such as mVRRP and VRRP association, perform the configurations according to the following sections.

Table 24-5 describes the VRRP configuration tasks.

Table 24-5  VRRP configuration task summary




Configure basic functions of an IPv4 VRRP group

You can configure an IPv4 VRRP group to implement gateway backup and ensure stable and efficient data forwarding.

Configuring Basic Functions of an IPv4 VRRP Group

Configure an IPv4 mVRRP group

An mVRRP group can be bound to service VRRP groups and can determine the status of a service VRRP group based on the binding. mVRRP is used when multiple VRRP groups coexist and helps decrease the number of VRRP packets to be sent and minimize network bandwidth consumption.

Configuring an IPv4 mVRRP Group

Configure association between VRRP and BFD to implement a rapid active/standby VRRP switchover

A VRRP IPv4 backup group can be configured to track BFD sessions. If one of the BFD sessions changes its status, the BFD module notifies the VRRP IPv4 backup group of the change. After receiving the notification, the VRRP IPv4 backup group rapidly performs a master/backup VRRP switchover.

Configuring Association Between VRRP and BFD to Implement a Rapid Active/Standby Switchover

Configure association between VRRP and the interface status

When the uplink interface of the master becomes faulty, VRRP cannot detect the status change of interfaces not in the VRRP group. This may interrupt services. You can associate a VRRP group with the interface status. When the monitored interface is faulty, the priority of the master is adjusted. This triggers an active/standby switchover and reduces the impact of services on the uplink interface.

Configuring Association Between VRRP and the Interface Status

Configure association between VRRP and BFD to monitor the uplink status

Because VRRP cannot detect faults on the uplink of the VRRP group, services may be interrupted. You can associate a VRRP group with a BFD session on the master so that the BFD session monitors the uplink status of the master. When the BFD session detects faults on the uplink, it notifies the VRRP group that the priority of the master needs to be decreased. Then an active/standby switchover is triggered immediately. This reduces the impact of uplink faults on service forwarding.

BFD implements millisecond-level detection. Association between VRRP and BFD provides fast active/standby switchover.
