When Switch A fails, you can still successfully ping Host B on Host A. To view the detailed 
information about the VRRP group on Switch B, use the display vrrp ipv6 verbose command.

•  When 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. 
•   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, and specify the 
authentication key as  hello.

become the master.
