# Configure the default gateway address of Host A to 10.1.1.111 and the default gateway address
of Host B to 20.1.1.1.
Step 3
Configure a VRRP group.
# On Switch A, assign an IP address to the VLANIF interface. Create VRRP group 1 and set
the priority of Switch A in the VRRP group to 120 so that Switch A functions as the master.

vrrp vrid 1 virtual-ip 10.1.1.111

vrrp vrid 1 preempt-mode timer delay 20
[SwitchA-Vlanif100]
quit
# On Switch B, assign an IP address to the VLANIF interface. Create VRRP group 1 and retain
the default priority of SwitchB in the VRRP group so that Switch B functions as the backup.

interface vlanif 100
[SwitchB-Vlanif100]
vrrp vrid 1 virtual-ip 10.1.1.111

quit
Step 4
Verify the configuration.
l
The VRRP group can function as the gateway.
After the preceding configuration, Host A can ping Host B. Run the
display vrrp
command on
Switch A, and you can find that Switch A is the master switch. Run the
display vrrp
command
on Switch B, and you can find that Switch B is the backup switch.
