4.4.6 Checking the Configurations
After configuring VRRP IPv4 association, you can view the status of a tracked BFD or EFM
session and verify the configuration.
Prerequisites
The configurations of VRRP IPv4 association are complete.
Procedure
l
Run the
display vrrp
[
interface
interface-type
interface-number
[

] ]
command to check the status and configurations of a specified VRRP backup group.
----End
Example
Run the
display vrrp
command. The command output shows that the BFD session and the EFM
session tracked by the VRRP IPv4 backup group is

4.5 Configuring the Rapid VRRP Switchback Function
After the original master device recovers, the rapid VRRP switchback function enables the
original master device to increase its priority to be higher than the existing master device and
immediately switch to the Master state.
Usage Scenario
A master device in a VRRP backup group tracks a VRRP-disabled interface or a feature such
as a BFD session and reduces its VRRP priority if the tracked interface or feature status changes
due to a fault. The priority reduction triggers a master/backup VRRP switchover. On the network
shown in
, VRRP-enabled NPEs are connected to user-side PEs through active and
