大型综合网络搭建详细步骤教程

1.1 问题
现有网络问题分析：

接入层交换机只与同一个三层交换机相连，存在单点故障而影响网络通信。
互联网连接单一服务商
现有网络需求：

随着企业发展，为了保证网络的高可用性，需要使用很多的冗余技术
保证局域网络不会因为线路故障而导致的网络故障
保证客户端机器不会因为使用单一网关而出现的单点失败
保证到互联网的高可用接入使用冗余互联网连接
1.2 方案
基于项目的需求，需要用到如下技术：

OSPF路由协议：实现网络路径的自动学习
VRRP：实现网关冗余
重新规划后的网络拓扑如图-1：

1.3 步骤
实现此案例需要按照如下步骤进行，为了配置过程中不被弹出信息干扰，可以关闭信息提示
