# Configure Router B to work in preemptive mode, so that Router B can become the master after the

priority of Router A decreases to a value lower than 100. Configure the preemption delay as five
seconds to avoid frequent status switchover.

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.
