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
•
Host A needs to access Host B on the Internet, using 1::10/64 as its default gateway.
•
Switch A and Switch B belong to VRRP group 1 with the virtual IP addresses of 1::10/64
and FE80::10.
•
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.
