# Configure the authentication mode of the VRRP group as simple and authentication key as
hello.
[RouterB-GigabitEthernet1/0/2] vrrp vrid 1 authentication-mode simple hello
# Configure the master to send VRRP packets every 4 seconds.
[RouterB-GigabitEthernet1/0/2] vrrp vrid 1 timer advertise 4
# Configure Router B to operate 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 5 seconds to avoid frequent status switchover.
[RouterB-GigabitEthernet1/0/2] vrrp vrid 1 preempt-mode timer delay 5
