Data Preparation
To complete the configuration, you need the following data:

Procedure
Step 1 Assign an IP address to each interface to ensure link connectivity on the network.
For details, see
Step 2 Create a VRRP backup group and configure its basic functions.
# Create VRRP backup group 10 and set the VRRP priority to 160 on Router A so that Router
A is the Master.
[RouterA] interface gigabitethernet 2/0/0
[RouterA-GigabitEthernet2/0/0] vrrp vrid 10 virtual-ip 10.1.1.3
[RouterA-GigabitEthernet2/0/0] vrrp vrid 10 priority 160
[RouterA-GigabitEthernet2/0/0] quit
# Create VRRP backup group 10 and set the VRRP priority to 140 on Router B so that Router
B is the Backup.
[RouterB] interface gigabitethernet2/0/0
[RouterB-GigabitEthernet2/0/0] vrrp vrid 10 virtual-ip 10.1.1.3
[RouterB-GigabitEthernet2/0/0] vrrp vrid 10 priority 140

Assign an IP address to each interface to ensure IP connectivity.
Configure a VRRP backup group on GE interfaces of Router A and Router B. Ensure that
Router A is the Master and Router B is the Backup so that a master/backup VRRP
switchover can be performed and Router B can take over traffic if a link connected to
Router A fails.
Configure a peer BFD session on Router A and Router B to monitor the link between
Router A and Router B.
Configure a VRRP backup group on Router B to track the BFD session and allow Router
B to increase its VRRP priority by 40 to trigger a master/backup VRRP switchover if the
BFD session goes Down.
NOTE
l This example only provides configurations on Router A and Router B.
l To implement a rapid traffic switchover if Router A fails, change item three in "Configuration
Roadmap" to configure a BFD session on POS interfaces directly connecting Router A and Router B.
The configuration is not provided in this example.
IP address of each interface on Router A and Router B (For details, see
Files.)
VRID (10), virtual IP address (10.1.1.3), VRRP priorities (160 for Router A and 140 for
Router B), and value (40) by which Router B increases its VRRP priority and preempts the
Master if a link fails
