The above information indicates that in VRRP group 1 Switch A is the master, Switch B is the backup
and hosts with the default gateway of 1::10/64 accesses the Internet through Switch A; in VRRP group
2 Switch A is the backup, Switch B is the master and hosts with the default gateway of 2::10/64
accesses the Internet through Switch B.
Multiple VRRP groups are commonly used in actual networking. In IPv6 network, to implement load
sharing among multiple VRRP groups, you need to manually configure the default gateway for hosts.
VRRP Load Balancing Mode Configuration Example
Network requirements
Switch A, Switch B, and Switch C belong to VRRP group 1 with the virtual IPv6 address of
FE80::10.
Hosts on network segment 1::/64 use FE80::10 as their default gateway. Use the VRRP group to
ensure that when a gateway (Switch A, Switch B, or Switch C) fails, the hosts on the LAN can
access the external network through another gateway.
VRRP group 1 works in the load balancing mode to make good use of network resources.
