The output shows that if Router A fails, Router B becomes the master, and packets sent from
host A to host B are forwarded by Router B.
# After Router A resumes normal operation, use the display vrrp verbose command to display
the detailed information about VRRP group 1 on Router A.

VRRP interface tracking configuration example

Network requirements
•
Host A wants to access Host B on the Internet, using 202.38.160.111/24 as its default gateway.
•
Router A and Router B belong to VRRP group 1 with the virtual IP address of
202.38.160.111/24.
•
When Router A operates correctly, packets sent from Host A to Host B are forwarded by Router
A. When interface GigabitEthernet 1/0/1 through which Router A connects to the Internet is not
available, packets sent from Host A to Host B are forwarded by Router B.
•
To prevent attacks to the VRRP group from illegal users by using spoofed packets, configure
the authentication mode as plain text to authenticate the VRRP packets in VRRP group 1.
Specify the authentication key as hello.
