题目：静态路由器的配置
组 员： 专 业：电气工程及其自动化 学生邮箱：
一、实验要求
掌握静态路由方式实现网络的连通性。
二、技术原理
路由器属于网络层设备，能够根据IP包头的信息，选择一条最佳路径，将数据包装发出去。实现不同网段的主机之间的互相访问。
路由器是根据路由表进行选路好转发的。而路由表里就是由一条条的路由信息组成。路由表的产生方式一般有3种：
➢ 直接路由-----给路由器接口配置一个IP地址，路由器自动产生本接口IP所在网段的路由
信息。
➢ 静态路由-----在拓扑结构简单的网络中，网管员通过手工的方式配置本路由器未知网段
的路由信息，从而实现不同网段之间的链接。
➢ 动态路由协议学习产生的路由-----在大规模的网络中，或网络拓扑结构相对复杂的情况
下，通过在路由器上运行动态路由协议，路由器之间互相自动学习产生路由信息。
三、实现功能
实现网络的互连互通，从而实现信息的共享和传递。
四、实验设备
R1762（两台）、V35线缆（1条）、PC（两台）、直连线或者交叉线（2条）
五、实验拓扑
图中各端口的IP地址为： R1200-1：

七、注意事项
如果两台路由器通过串口直接互连，必须在其中一段设置时钟频率。
八、心得体会
通过本次的实验，学会了如何配置静态路由，对网络之间的相互通信有了更深一步的了解和认识。
在实验中，需要格外的注意连线，因为我们做实验的过程中遇到接口接触不良的情况，在PC上显示线路未连接，而连错线的时候PC也是显示线路未连接，所以要注意区分这两种情况，找到原因，纠正连线。否则会浪费较多的时间。
