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.

Configure Switch A
# Configure VLAN 2.

[SwitchA-Vlan-interface2] ipv6 address 1::1 64
# Create VRRP group 1 and set its virtual IPv6 addresses to FE80::10 to 1::10.
[SwitchA-Vlan-interface2] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local
[SwitchA-Vlan-interface2] vrrp ipv6 vrid 1 virtual-ip 1::10
# Set the priority of Switch A in VRRP group 1 to 110, which is higher than that of Switch B (100), so that
Switch A can become the master in VRRP group 1.
[SwitchA-Vlan-interface2] vrrp ipv6 vrid 1 priority 110
[SwitchA-Vlan-interface2] quit
# Enable Switch A to send RA messages, so that hosts in VLAN 2 can learn the default gateway address.
[SwitchA-Vlan-interface2] undo ipv6 nd ra halt
[SwitchA-Vlan-interface2] quit
# Configure VLAN 3.
