VRRP load balancing configuration example
Network requirements
Switch A, Switch B, and Switch C form a load balanced VRRP group and use the virtual IPv6
addresses FE80::10 and 1::10 to provide gateway service for subnet 1::/64, as shown in Figure 42.
Ho
sts on subnet 1::/64 learn 1::10 as their default gateway from RA messages sent by the switches.
Configure VFs on Switch A, Switch B, or Switch C to monitor their respective VLAN-interface 3.
When the interface on any of them fails, the weights of the VFs on the problematic switch decrease
so another AVF can take over.

Configuration procedure
1. Configure Switch A:
# Configure VLAN 2.
<SwitchA> system-view
[SwitchA] vlan 2
[SwitchA-vlan2] port ten-gigabitethernet 1/0/5
[SwitchA-vlan2] quit
# Configure VRRP to operate in load balancing mode.
[SwitchA] vrrp ipv6 mode load-balance
# Create VRRP group 1, and set its virtual IPv6 addresses to FE80::10 and 1::10.
[SwitchA] interface vlan-interface 2
[SwitchA-Vlan-interface2] ipv6 address fe80::1 link-local
[SwitchA-Vlan-interface2] ipv6 address 1::1 64
[SwitchA-Vlan-interface2] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local
[SwitchA-Vlan-interface2] vrrp ipv6 vrid 1 virtual-ip 1::10
IP: 1::4/64
Gateway IP: 1::10
