The output shows that when Switch A fails, Switch B takes over to forward packets from Host A
to Host B.

Multiple VRRP groups configuration example
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 38.
Assig
n 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.
