# Configure LB A to operate in preemptive mode so that it can become the master whenever it

works properly; configure the preemption delay as five seconds to avoid frequent status
switchover.

[LBB] ipv6

[LBB] interface gigabitethernet0/1

[LBB-GigabitEthernet0/1] ipv6 address fe80::2 link-local

[LBB-GigabitEthernet0/1] ipv6 address 1::2 64

# Create a VRRP group 1 and set its virtual IPv6 addresses to FE80::10 and 1::10.

[LBB-GigabitEthernet0/1] vrrp ipv6 vrid 1 virtual-ip 1::10

# Configure LB B to operate in preemptive mode, with the preemption delay set to five seconds.

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.
