Multiple VRRP groups configuration example
This section provides an example of configuring multiple VRRP groups on switches.
Network requirements
Switch A and Switch B form two VRRP groups. VRRP group 1 uses the virtual IP address 10.1.1.100/25 to
provide gateway service for hosts in VLAN 2, and VRRP group 2 uses the virtual IP address
10.1.1.200/25 to provide gateway service for hosts in VLAN 3, as shown in
Figure 16 .
Assign a higher priority to Switch A than Switch B in VRRP group 1, but a lower priority in VRRP group
2, to distribute the traffic from VLAN 2 and VLAN 3 between the two switches. When one of the switches
fails, the healthy switch provides gateway service for both VLANs.

Configuration procedure
1. Configure Switch A:
# Configure VLAN 2.
system-view
[SwitchA] vlan 2
[SwitchA-vlan2] port fortygige 1/0/5
[SwitchA-vlan2] quit
[SwitchA] interface vlan-interface 2
[SwitchA-Vlan-interface2] ip address 10.1.1.1 255.255.255.128
# Create VRRP group 1, and set its virtual IP address to 10.1.1.100.
[SwitchA-Vlan-interface2] vrrp vrid 1 virtual-ip 10.1.1.100
# Assign Switch A a higher priority than Switch B in VRRP group 1, so Switch A can become the
master in the group.
[SwitchA-Vlan-interface2] vrrp vrid 1 priority 110
[SwitchA-Vlan-interface2] quit
# Configure VLAN 3.
[SwitchA] vlan 3
[SwitchA-vlan3] port fortygige 1/0/6
[SwitchA-vlan3] quit
