The above information shows that when 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.
VRRP with Multiple VLANs Configuration Example
Network requirements
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 Hosts in VLAN 2 learn 1::10/64 as their default gateway and hosts in VLAN 3 learn 2::10/64
as their default gateway through RA messages sent by the switches.
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 external networks through Switch A and Switch B respectively, and when
Switch A or Switch B fails, the hosts can use the other switch to communicate with external
networks to avoid communication interruption.
