the external network through another gateway.

• VRRP group 1 works in the load balancing mode to make good use of network resources.

2. Configure LB A

# Configure VRRP to work in the load balancing mode.

<LB A> system-view

[LB A] vrrp mode load-balance

# Create VRRP group 1 and configure its virtual IP address as 10.1.1.1.

[LB A] interface Ten-GigabitEthernet 0/0.1

[LB A-Ten-GigabitEthernet0/0.1] ip address 10.1.1.2 24

[LB A-Ten-GigabitEthernet0/0.1] vrrp vrid 1 virtual-ip 10.1.1.1

# Set the priority of LB A in VRRP group 1 to 120.

[LB A-Ten-GigabitEthernet0/0.1] vrrp vrid 1 priority 120

# Set LB A to work in preemptive mode. The preemption delay is five seconds.
