The virtual router can be used soon after configuration. Host A can be configured with
the default gateway 202.38.160.111.
Under normal conditions, switch A functions as the gateway. Once switch A breaks
down, switch B will function as the gateway instead.
Configure the preemption mode for switch A, so that it can become the master again
after recovery.

should function as the gateway. This can be implemented by tracking the
corresponding interface.
The virtual router ID is 1. In addition, the MD5 authentication and VRRP packet sending
interval are configured.

III. Configuration procedure
1) Configure switch A
# Configure VLAN2.
[LSW-A] vlan 2
[LSW-A-vlan2] interface vlan 2
[LSW-A-vlan-interface2] ip address 202.38.160.1 255.255.255.0
[LSW-A-vlan-interface2] quit
# Enable the function to ping the virtual IP address of the virtual router.
