master节点拥有VIP的绑定权,负责处理发送给vip的数据包
1)vrrp基于多播,master节点每隔Advertisement_Interval(默认1s)发送一次广播,backup节点Master_Down_Interval=(3 * Advertisement_Interval) +((256-Priority)/256 )间隔后还没收到master的广播,就会认为master挂了。然后自己转换为master节点.
2)当master节点有计划地退出、发送Priority=0的广播,当backup节点收到master接单发送的priority=0的广播后,将Master_Down_Interval设置为skew_time=((256-Priority)/256 )),尽快超时
