华为VRRP和浮动路由配置与应用

VRRP：虚拟 路由器 冗余 协议virtual router redundancy protocol V

.

VRRP：
虚拟 路由器 冗余 协议
virtual router redundancy protocol

VRRP ：(公有协议)
在多个路由器之间运行，
可以虚拟出一个或者多个网关IP地址(虚拟路由器)；
从而实现内网不同网段之间的互通；

VRRP的工作过程：
1、运行VRRP的“多个”路由器之间通过 VRRP 报文的交互，从而选择
出一个最牛的路由器，作为 Master 路由器 ，以后就用来这个设备
来转发数据包；
2、Master 路由器，仅仅只有一个；其他的路由器称之为 backup 路由器；
3、同时，Master 和 Backup 路由器，会产生一个虚拟的路由器，也就是一个
虚拟的IP地址；
