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.
Multiple VRRP Group Configuration Example
Network requirements
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.
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.
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.
