Master IP : FE80::1
The above information indicates that in VRRP group 1 Device A is the master, Device B is the backup and
packets sent from Host A to Host B are forwarded by Device A.
If Device A fails, you can still ping Device B successfully on Host A. To view the detailed information of
the VRRP group on Device B, use the display vrrp ipv6 verbose command.
# If Device A fails, the detailed information of VRRP group 1 on Device B is displayed.

The above information indicates that if Device A fails, Device B becomes the master, and packets sent
from Host A to Host B are forwarded by Device B.
VRRP Interface Tracking Configuration Example
Network requirements
• Host A needs to access Host B on the Internet, using 1::10/64 as its default gateway.
• Device A and Device B belong to VRRP group 1 with the virtual IPv6 addresses of 1::10/64 and
FE80::10.
• If Device A operates normally, packets sent from Host A to Host B are forwarded by Device A; if
interface GigabitEthernet 0/1 through which Device A connects to the internet is not available,
packets sent from Host A to Host B are forwarded by Device B.
