The output shows that when Switch A fails, Switch B becomes the master, and packets sent from 
Host A to Host B are forwarded by Switch B. 
# After Switch A resumes normal operation, use the  display vrrp verbose command to display the

The output shows that in VRRP group 1 Switch A is the master, Switch B is the backup and packets 
sent from Host A to Host B are forwarded by Switch A.

VRRP with multiple VLANs configuration example 
Network requirements 
•  Hosts in VLAN 2 use 202.38.160.100/25 as their default gateway and hosts in VLAN 3 use 
202.38.160.200/25 as their default gateway. 
•   Switch A and Switch B belong to both VRRP group 1 and VRRP group 2. The virtual IP address of 
VRRP group 1 is 202.38.160.100/25, and that of VRRP group 2 is 202.38.160.200/25. 
•   In VRRP group 1, Switch A has a higher priority than Switch B. In VRRP group 2, Switch B has a 
higher priority...
