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

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；

热备份路由协议中思科HSRP与华为VRRP的配置实例及区别

首先用思科的HSRP热备份路由协议配置. 首先在为这个拓扑配置命令前先分析一下这个拓扑图,了解它的实验目的及要求与想要达成的效果. 然后在看需要为这拓扑配置的命令. 分析拓扑图:(不论配置协议实现全网互通是首要条件) R1路由端口配置地址并激活, 添加loopback口配置地址, 配置到C1机的静态路由. R2活跃路由端口配置地址并激活, 接交换机的口配置双工, 配置到loopback口的默认路由或到loopback口的静态路由(只要一个就行), 做HSRP热备份路由改路由为活跃路由. R3
