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 21
.
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.
