<RouterA> system-view

[RouterA] interface gigabitethernet 2/0/1

# Create VRRP group 1, and configure the virtual IP address 192.168.0.10 for the group.

[RouterA-GigabitEthernet2/0/1] vrrp vrid 1 virtual-ip 192.168.0.10

# Set the priority of Router A in VRRP group 1 to 110.

[RouterA-GigabitEthernet2/0/1] vrrp vrid 1 priority 110

[RouterA-GigabitEthernet2/0/1] return

2. Configure BFD on Router B:

# Configure the source address of BFD echo packets as 10.10.10.10.

<RouterB> system-view

[RouterB] bfd echo-source-ip 10.10.10.10

# Create track entry 1, and associate it with the BFD session to verify the reachability of Router A.

[RouterB] track 1 bfd echo interface gigabitethernet 2/0/1 remote ip 192.168.0.101

local ip 192.168.0.102

3. Configure VRRP on Router B:

# Create VRRP group 1, and configure the virtual IP address 192.168.0.10 for the group.

[RouterB] interface gigabitethernet 2/0/1

[RouterB-GigabitEthernet2/0/1] vrrp vrid 1 virtual-ip 192.168.0.10

# Associate VRRP group 1 with track entry 1.

[RouterB-GigabitEthernet2/0/1] vrrp vrid 1 track 1 switchover
