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.
# After Router A resumes normal operation, use the display vrrp ipv6 verbose command to display

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 Ethernet 1/1 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.
