OSPF动态路由
- 一、题目要求
- 二、题目分析
- 三、拓扑结构
- 四、基础配置
- 五、测试验证

一、题目要求

1 、使用172.16.0.0.0/16网段进行子网划分
2 、用OSPF协议达到全网可达
3 、保证所有设备均具备最少的 LSDB 以及路由表
在这里插入图片描述

二、题目分析

1.网段划分

5个OSPF区域和1个RIP区域，先划分6个网段,然后再分为：area0：8个网段，area1：4个网段，area2：3个网段，RIP：2个网段，area3：3个网段，area4：3个网段，划分详情见拓扑结构；

2.在R7与R11上设置虚链路

3.在R9上做双向重发布

三、拓扑结构

在这里插入图片描述

四、基础配置
