Configuration procedure
1) Configure Switch A
# Configure VLAN 2.
<SwitchA> system-view
[SwitchA] ipv6
[SwitchA] vlan 2
[SwitchA-vlan2] port gigabitethernet 2/0/5
[SwitchA-vlan2] quit
[SwitchA] interface vlan-interface 2
[SwitchA-Vlan-interface2] ipv6 address fe80::1 link-local
[SwitchA-Vlan-interface2] ipv6 address 1::1 64
# Create a VRRP group 1 and set its virtual IPv6 addresses to FE80::10 and 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.
[SwitchA-Vlan-interface2] vrrp ipv6 vrid 1 priority 110
# Configure Switch A to work in preemptive mode so that it can become the master whenever it
works normally, and configure the preemption delay as five seconds to avoid frequent status
switchover.
[SwitchA-Vlan-interface2] vrrp ipv6 vrid 1 preempt-mode timer delay 5
# Enable Switch A to send RA messages, so that Host A can learn the default gateway address.
[SwitchA-Vlan-interface2] undo ipv6 nd ra halt
2) Configure Switch B
# Configure VLAN 2.
<SwitchB> system-view
[SwitchB] ipv6
[SwitchB] vlan 2
[SwitchB-vlan2] port gigabitethernet 2/0/5
