1-44 

     Preempt Mode   : Yes                  Delay Time   : 5 

     Auth Type      : Simple               Key          : hello 

     Virtual IP     : FE80::10 

                      1::10 

     Virtual MAC    : 0000-5e00-0201 

     Master IP      : FE80::2 

The above information indicates that if VLAN-interface 3 on Switch A is not available, the priority of 

Switch A is reduced to 80 and Switch A becomes the backup. Switch B becomes the master and 

packets sent from Host A to Host B are forwarded by Switch B. 

z 

Hosts in VLAN 2 use 1::10/64 as their default gateway and hosts in VLAN 3 use 2::10/64 as their 

default gateway. 

z 

Switch A and Switch B belong to both VRRP group 1 and VRRP group 2. The virtual IPv6 

addresses of VRRP group 1 are 1::10/64 and FE80::10, and those of VRRP group 2 are 2::10/64 

and FE90::10. 

z 

In VRRP group 1, Switch A has a higher priority than Switch B. In VRRP group 2, Switch B has a 

higher priority than Switch A. In this case, hosts in VLAN 1 and VLAN can communicate with the 

outside through Switch A and Switch B respectively, and if Switch A or Switch B fails, the hosts can 

use the other switch to communicate with the outside, so as to avoid communication interruption.
