The output shows that when Router A fails, Router B becomes the master, and packets sent
from Host A to Host B are forwarded by Router B.

VRRP interface tracking configuration example

Network requirements
•
Router A and Router B belong to VRRP group 1 with the virtual IPv6 addresses of 1::10/64 and
FE80::10.
•
Host A wants to access Host B on the Internet, and learns 1::10/64 as its default gateway
through RA messages sent by the routers.
•
When Router A operates correctly, Router A forwards the packets that Host A sends to Host B. If
interface GigabitEthernet 1/0/1 through which Router A connects to the Internet is not available,
Router B forwards the packets that Host A sends to Host 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.
