[RouterA] vrrp mode load-balance

# Create VRRP group 1, and set its virtual IP address to 10.1.1.1.

[RouterA] interface gigabitethernet 2/0/1

[RouterA-GigabitEthernet2/0/1] ip address 10.1.1.2 24

[RouterA-GigabitEthernet2/0/1] vrrp vrid 1 virtual-ip 10.1.1.1

# Assign Router A the highest priority in VRRP group 1, so Router A can become the master.

[RouterA-GigabitEthernet2/0/1] vrrp vrid 1 priority 120

# Configure Router A to operate in preemptive mode, so it can become the master whenever it

operates correctly. Set the preemption delay to 5 seconds to avoid frequent status switchover.

[RouterA-GigabitEthernet2/0/1] vrrp vrid 1 preempt-mode delay 5

[RouterA-GigabitEthernet2/0/1] quit

# Create track entry 1 to monitor the upstream link status of GigabitEthernet 2/0/2. When the

upstream link fails, the track entry transits to Negative.

[RouterA] track 1 interface gigabitethernet 2/0/2

# Configure the VFs in VRRP group 1 to monitor track entry 1, and decrease their weights by 250

when the track entry transits to Negative.

[RouterA] interface gigabitethernet 2/0/1

[RouterA-GigabitEthernet2/0/1] vrrp vrid 1 weight track 1 reduced 250

2. Configure Router B:

# Configure VRRP to operate in load balancing mode.

<RouterB> system-view

[RouterB] vrrp mode load-balance

# Create VRRP group 1, and set its virtual IP address to 10.1.1.1.

[RouterB] interface gigabitethernet 2/0/1

[RouterB-GigabitEthernet2/0/1] ip address 10.1.1.3 24

[RouterB-GigabitEthernet2/0/1] vrrp vrid 1 virtual-ip 10.1.1.1

# Assign Router B a higher priority than Router C in VRRP group 1, so Router B can become the

master when Router A fails.

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

# Configure Router B to operate in preemptive mode, and set the preemption delay to 5 seconds.

[RouterB-GigabitEthernet2/0/1] vrrp vrid 1 preempt-mode delay 5

[RouterB-GigabitEthernet2/0/1] quit

# Create track entry 1 to monitor the upstream link status of GigabitEthernet 2/0/2. When the

upstream link fails, the track entry transits to Negative.

[RouterB] track 1 interface gigabitethernet 2/0/2

# Configure the VFs in VRRP group 1 to monitor track entry 1, and decrease their weights by 250

when the track entry transits to Negative.

[RouterB] interface gigabitethernet 2/0/1

[RouterB-GigabitEthernet2/0/1] vrrp vrid 1 weight track 1 reduced 250

3. Configure Router C:

# Configure VRRP to operate in load balancing mode.

<RouterC> system-view

[RouterC] vrrp mode load-balance

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