HSRP??

hsrp状态：

init：hsrp的初始状态

learn：学习虚拟ip，如果有个配置了虚拟ip，有个没去配置，那个没配的会学习虚拟ip

listen：监听是否存在活跃路由器，hsrp默认是越早启动的路由器越能成为活跃路由器

以上几个状态都没有发送hello包

speak：发送hello包，包含自己的hsrp的各种参数

backup：组内备份路由器所处的状态，备份组员监视活动路由器，准备随时在活动路由器坏掉，时接替活动路由器。

备份路由器也周期性发送 Hello 报文告诉其他组员自己没有坏掉。

active：组内活动路由器即负责虚拟路由器实际路由工作的组员所处的状态。

活动路由器周期性发送 Hello 报文告诉其他组员自己没有坏掉。

下面这个是R3先启动hsrp，hsrp虚拟ip是192.168.2.1，R4后启动，并且没有配置
