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 associations, perform the following configurations.

Table 3-4 describes the VRRP configuration tasks.

Scenario

Description

Task

Configure basic functions of a VRRP group

You can configure a VRRP group to implement gateway backup and ensure stable and highly-efficient data forwarding.

Configure an mVRRP group

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

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

A VRRP group can be configured to monitor a BFD session. When the BFD session status changes, BFD notifies the VRRP group of the change. After receiving the notification, the VRRP group rapidly performs an 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.

Configure association between VRRP and BFD/NQA/routing to monitor the uplink status

Because VRRP cannot detect faults on the uplink of a VRRP group, services may be interrupted. Association between VRRP and BFD/NQA/routing allows the device to detect faults on the uplink of the master. When the uplink of the master fails, BFD/NQA/routing rapidly detects the fault and instructs the master to adjust its priority. This triggers an active/standby switchover and ensures proper traffic forwarding.

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

NQA technology collects statistics on the delay, jitter, and packet loss ratio. You can configure the percentage of failed NQA test instances and NQA association to trigger an active/standby switchover when the uplink is unstable.
