# Configure VLAN2.
[LSW-B] vlan 2
[LSW-B-vlan2] interface vlan 2

# Enable the function to ping the virtual IP address of the virtual router.
[H3CLSW-B] vrrp ping-enable
# Create the virtual router.
[LSW-B] interface vlan 2
[LSW_B-vlan-interface2] vrrp vrid 1 virtual-ip 202.38.160.111
# Set the authentication mode and authentication key for the virtual router.

Under normal conditions, switch A functions as the gateway. Once VLAN-interface 3 of
switch A is down, its priority will be reduced by 30, lower than that of switch B so that
switch B will become the master.
When VLAN-interface 3 of switch A recovers, it will become the master again.
