[SwitchB-Vlan-interface2] display vrrp ipv6 verbose
IPv6 Standby Information:
Run Mode : Standard
Run Method : Virtual MAC
Total number of virtual routers : 1
Interface Vlan-interface2
VRID : 1 Adver Timer : 100
Admin Status : Up State : Master
Config Pri : 100 Running Pri : 100

Auth Type : None
Virtual IP : FE80::10
1::10
Virtual MAC : 0000-5e00-0201
Master IP : FE80::2
The above information shows that when Switch A fails, Switch B becomes the master, and
packets sent from Host A to Host B are forwarded by Switch B.
# After Switch A resumes normal operation, use the display vrrp ipv6 verbose command to
display the detailed information of VRRP group 1 on Switch A.

VRRP Interface Tracking Configuration Example
Network requirements
z Switch A and Switch B belong to VRRP group 1 with the virtual IP addresses of 1::10/64
and FE80::10.
z 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 switches.
z 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.
