Host A learns 1::10/64 as its default gateway from RA messages sent by the switches.
Switch A operates as the master to forward packets from Host A to Host B. When Switch A fails, Switch
B takes over to forward packets for Host A.

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
[SwitchA] interface vlan-interface 2
[SwitchA-Vlan-interface2] ipv6 address fe80::1 link-local
[SwitchA-Vlan-interface2] ipv6 address 1::1 64
# Create 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
# Assign Switch A a higher priority than Switch B in VRRP group 1, so Switch A can become the
master.
[SwitchA-Vlan-interface2] vrrp ipv6 vrid 1 priority 110
# Configure Switch A to operate in preemptive mode, so it can become the master whenever it
operates correctly, and set the preemption delay to 5 seconds to avoid frequent status switchover.
[SwitchA-Vlan-interface2] vrrp ipv6 vrid 1 preempt-mode delay 5
# Enable Switch A to send RA messages, so 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] vlan 2
[SwitchB-vlan2] port ten-gigabitethernet 1/0/5
[SwitchB-vlan2] quit
