Which of the following statements are false about VRRP timers?

A is false– The correct formula is: Skew_Time = (256 - Priority)/256 × Advertisement_Interval.

B is false– By default, thepreemption delayis typically0s, not 1s, meaning a higher-priority backup router can preempt immediately unless configured otherwise.

C is true– Thedefault Advertisement intervalin VRRP is2 seconds.

D is true– The formula Master_Down_Interval = 3 × Advertisement_Interval + Skew_Time is correct.

Reference from Huawei HCIP-Datacom-Core Technology Study Guide:

“The VRRP Skew_Time is calculated as (256 - Priority)/256 × Adver_Interval. The Master_Down interval includes this Skew_Time to stagger failover.”
