Multiple VRRP groups configuration example
To implement load sharing between the VRRP groups, manually configure the default gateway 10.1.1.111 for some hosts and 10.1.1.112 for the other on the subnet 10.1.1.0/24.
Network requirements
As shown in Figure 24, Router A and Router B form two VRRP groups to implement load sharing and mutual backup. VRRP group 1 uses the virtual IP address 10.1.1.111/24 to provide gateway service for some hosts on the subnet 10.1.1.0/24. VRRP group 2 uses the virtual IP address 10.1.1.112/24 to provide gateway service for the other hosts on the subnet.

Configuration procedure
Configure Router A:
# Specify an IP address for Router A.
<RouterA> system-view [RouterA] interface gigabitethernet 1/0/1 [RouterA-GigabitEthernet1/0/1] ip address 10.1.1.1 255.255.255.0
# Create VRRP group 1 and set its virtual IP address to 10.1.1.111.
[RouterA-GigabitEthernet1/0/1] vrrp vrid 1 virtual-ip 10.1.1.111
# Assign Router A a higher priority than Router B in VRRP group 1, so Router A can become the master in the group.
[RouterA-GigabitEthernet1/0/1] vrrp vrid 1 priority 110
# Create VRRP group 2, and set its virtual IP address to 10.1.1.112.
[RouterA-GigabitEthernet1/0/1] vrrp vrid 2 virtual-ip 10.1.1.112
Configure Router B:
# Specify an IP address for Router B.
<RouterB> system-view [RouterB] interface gigabitethernet 1/0/1 [RouterB-GigabitEthernet1/0/1] ip address 10.1.1.2 255.255.255.0
# Create VRRP group 1, and set its virtual IP address to 10.1.1.111.
[RouterB-GigabitEthernet1/0/1] vrrp vrid 1 virtual-ip 10.1.1.111
# Create VRRP group 2, and set its virtual IP address to 10.1.1.112.
[RouterB-GigabitEthernet1/0/1] vrrp vrid 2 virtual-ip 10.1.1.112
# Assign Router B a higher priority than Router A in VRRP group 2, so Router B can become the master in the group.
[RouterB-GigabitEthernet1/0/1] vrrp vrid 2 priority 110

The output shows the following information:
Router A is operating as the master in VRRP group 1 to forward Internet traffic for hosts that use the default gateway 10.1.1.111/24.
Router B is operating as the master in VRRP group 2 to forward Internet traffic for hosts that use the default gateway 10.1.1.112/24.
