2. Configure LB A

<LB A> system-view

[LB A] interface Ten-GigabitEthernet 0/0.1

[LB A-Ten-GigabitEthernet0/0.1] ip address 202.38.160.1 255.255.255.0

# Create VRRP group 1 and configure its virtual IP address as 202.38.160.111.

[LB A-Ten-GigabitEthernet0/0.1] vrrp vrid 1 virtual-ip 202.38.160.111

# Configure the priority of LB A in the VRRP group 1 as 110.

[LB A-Ten-GigabitEthernet0/0.1] vrrp vrid 1 priority 110

# Configure LB A to work in preemptive mode and configure the preemption delay as five seconds.

[LB A-Ten-GigabitEthernet0/0.1] vrrp vrid 1 preempt-mode timer delay 5

3. Configure LB B

<LB B> system-view

[LB B] interface Ten-GigabitEthernet 0/0.1

[LB B-Ten-GigabitEthernet0/0.1] ip address 202.38.160.2 255.255.255.0

# Create VRRP group 1 and configure its virtual IP address as 202.38.160.111.

[LB B-Ten-GigabitEthernet0/0.1] vrrp vrid 1 virtual-ip 202.38.160.111

# Configure LB B to work in the preemptive mode, with the preemption delay set to 5 seconds.

[LB B-Ten-GigabitEthernet0/0.1] vrrp vrid 1 preempt-mode timer delay 5

4. Verify the configuration

After the configuration, Host B can be pinged through on Host A. You can use the display vrrp verbose

command to verify the configuration.

# Display detailed information of VRRP group 1 on LB A.

[LB A-Ten-GigabitEthernet0/0.1] display vrrp verbose
