# Set the authentication mode for VRRP group 1 to simple and authentication key to hello.
[SwitchA-Vlan-interface2] vrrp ipv6 vrid 1 authentication-mode simple hello
# Set the VRRP advertisement interval to 400 centiseconds.
[SwitchA-Vlan-interface2] vrrp ipv6 vrid 1 timer advertise 400
# Configure Switch A to operate in preemptive mode, so that it can become the master whenever
it works correctly; configure the preemption delay as 5 seconds to avoid frequent status
switchover.
[SwitchA-Vlan-interface2] vrrp ipv6 vrid 1 preempt-mode timer delay 5
# Set VLAN-interface 3 on Switch A to be tracked, and configure the amount by which the priority
value decreases to be more than 10 (30 in this example), so that when VLAN interface 3 fails, the
priority of Switch A in VRRP group 1 decreases to a value lower than 100 and thus Switch B can
become the master.
[SwitchA-Vlan-interface2] vrrp ipv6 vrid 1 track interface vlan-interface 3 reduced

# 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 3/0/5
[SwitchB-vlan2] quit
[SwitchB] interface vlan-interface 2
[SwitchB-Vlan-interface2] ipv6 address fe80::2 link-local
[SwitchB-Vlan-interface2] ipv6 address 1::2 64
# Create a VRRP group 1 and set its virtual IPv6 addresses to FE80::10 and 1::10.
[SwitchB-Vlan-interface2] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local
[SwitchB-Vlan-interface2] vrrp ipv6 vrid 1 virtual-ip 1::10
# Set the authentication mode for VRRP group 1 to simple and authentication key to hello.
[SwitchB-Vlan-interface2] vrrp ipv6 vrid 1 authentication-mode simple hello
# Set the VRRP advertisement interval to 400 centiseconds.
[SwitchB-Vlan-interface2] vrrp ipv6 vrid 1 timer advertise 400
# Configure Switch B to operate in preemptive mode, so that Switch B can become the master after
the priority of Switch A decreases to a value lower than 100. Configure the preemption delay as
5 seconds to avoid frequent status switchover.
[SwitchB-Vlan-interface2] vrrp ipv6 vrid 1 preempt-mode timer delay 5
# Enable Switch B to send RA messages, so that Host A can learn the default gateway address.
[SwitchB-Vlan-interface2] undo ipv6 nd ra halt
3. Verify the configuration:
After the configuration, Host B can be pinged successfully on Host A. To verify the configuration,
use the display vrrp ipv6 verbose command.
# Display the detailed information of VRRP group 1 on Switch A.
[SwitchA-Vlan-interface2] display vrrp ipv6 verbose
