The output shows that in VRRP group 1 Router A is the master, Router B is the backup and
packets sent from Host A to host B are forwarded by Router A.
If interface GigabitEthernet 1/0/1 through which Router A connects to the Internet is not
available, you can still successfully ping Host B on Host A. To view the detailed information
about the VRRP group, use the display vrrp verbose command.
# If interface GigabitEthernet 1/0/1 on Router A is not available, the detailed information about
VRRP group 1 on Router A is displayed.
