# Create VRRP group 1, and set its virtual IP address as 10.1.1.1.

# Create track entry 1 to monitor the upstream link status of Ethernet 1/2. When the upstream link

4. Verify the configuration:
# Verify that Host A can ping the external network. (Details not shown.)
# Display detailed information about VRRP group 1 on Router A.
