The output shows that when Switch A fails, Switch B takes over to forward packets from Host A to
Host B.
# Recover the link between Host A and Switch A, and display detailed information about VRRP
group 1 on Switch A.

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 17 .
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.
