实例如下图示：

HSRP
默认每3秒种发送一个hello消息。
standby <number> timers <间隔时间> <没收到的间隔时间切换>
如：
standby 39 timers 5 15 定义39组5秒交换一次hello信息，如15秒内没收到hello信息将开始切换。
config t
track <track-number> interface <interface-name> line-protocol
int vlan<number>
 standby <number> track <track-number>
如：
config t
track 1 interface FastEthernet0/1 line-protocol
int vlan39
 standby 39 track 1
