# Configure LB A to operate in preemptive mode, so that it can become the master whenever it
works properly. Set the preemption delay to five seconds to avoid frequent status switchover.

# Set GigabitEthernet 0/1 on LB 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 GigabitEthernet 0/1 fails,
the priority of LB A in VRRP group 1 decreases to a value lower than 100 and thus LB B can
become the master.

# Enable LB A to send RA messages, so that Host A can learn the default gateway address.

2. Configure LB B:
system-view
[LBB] ipv6
[LBB] interface gigabitethernet0/2
[LBB-GigabitEthernet0/2] ipv6 address fe80::2 link-local
[LBB-GigabitEthernet0/2] ipv6 address 1::2 64
# Create a VRRP group 1 and set its virtual IPv6 addresses to FE80::10 and 1::10.
[LBB-GigabitEthernet0/2] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local
[LBB-GigabitEthernet0/2] vrrp ipv6 vrid 1 virtual-ip 1::10
# Set the authentication mode of VRRP group 1 as simple and authentication key as hello.
[LBB-GigabitEthernet0/2] vrrp ipv6 vrid 1 authentication-mode simple hello
# Set the interval between sending VRRP advertisements to 400 centiseconds.
[LBB-GigabitEthernet0/2] vrrp ipv6 vrid 1 timer advertise 400
# Configure LB B to operate in preemptive mode, so that LB B can become the master after the
priority of LB A decreases to a value lower than 100. Configure the preemption delay as five
seconds to avoid frequent status switchover.
[LBB-GigabitEthernet0/2] vrrp ipv6 vrid 1 preempt-mode timer delay 5
# Enable LB B to send RA messages, so that Host A can learn the default gateway address.
[LBB-GigabitEthernet0/2] undo ipv6 nd ra halt
3. Verify the configuration:
After the configuration, Host B can be pinged successfully on Host A. To verify your configuration,
use the display vrrp ipv6 verbose command.
# Display the detailed information about VRRP group 1 on LB A.
[LBA-GigabitEthernet0/2] display vrrp ipv6 verbose
