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：

Ø 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。

Ø 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。

Ø 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：

F1/0:172.16.1.1/24 S1/2:172.16.2.1/24

R1200-2:

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:

Minimum = 0ms, Maximum = 0ms, Average = 0ms

C:\Documents and Settings\Administrator>ping 172.16.1.11

Pinging 172.16.1.11 with 32 bytes of data:

Reply from 172.16.1.11: bytes=32 time=20ms TTL=126

Ping statistics for 172.16.1.11:

Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

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。
