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

VRRP Interface Tracking Configuration Example
Network requirements
z
Host A needs to access Host B on the Internet, using 1::10/64 as its default gateway.
z
Switch A and Switch B belong to VRRP group 1 with the virtual IP addresses of 1::10/64 and
FE80::10.
z
If Switch A operates normally, packets sent from Host A to Host B are forwarded by Switch A; if
VLAN-interface 3 through which Switch A connects to the Internet is not available, packets sent
from Host A to Host B are forwarded by Switch B.
