Configuration Roadmap
Association between VRRP and BFD is used to implement fast switching of master and backup
gateways. The configuration roadmap is as follows:
1.
2.
3.
4.
Procedure
Step 1 Configure devices to ensure network connectivity.
# Assign an IP address to each interface and configure a routing protocol. RouterA is used as an
example. The configurations of RouterB and RouterC are similar to the configuration of
RouterA, and are not mentioned here.

Assign an IP address to each interface and configure a routing protocol to ensure network
connectivity.
Configure a VRRP group on RouterA and RouterB, set the priority of RouterA to 120 and
the preemption delay to 20s so that RouterA functions as the master, and set the default
priority for RouterB so that RouterB functions as the backup.
Configure a static BFD session on RouterA and RouterB to monitor the link of the VRRP
group.
Configure association between VRRP and BFD on RouterB. When the link is faulty, an
active/standby switchover can be performed rapidly.
