VRRP with multiple VLANs configuration example
Network requirements
• 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.
• 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.
