一、实验目标

  • 掌握静态路由的配置方法和技巧;
  • 掌握通过静态路由方式实现网络的连通性;
  • 熟悉广域网线缆的连接方式;

二、实验背景

学校有新旧两个校区,每个校区是一个独立的局域网,为了使新旧校区能够正常相互通讯,共享资源,每个校区出口利用一台路由器进行连接,两台路由器间学校申请了一条2M的DDN专线进行相连,要求你做适当配置实现两个校区间的正常相互访问。

三、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转发出去,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和转发的,而路由表就是由一条条路由信息组成。

生成路由表主要有两种方法:手工配置和动态配置,即静态路由协议配置和动态路由协议配置。

静态路由是指由网络管理员手工配置的路由信息。

静态路由除了具有简单、高效、可靠的优点外,它的另一个好处是网络安全保密性高。

缺省路由可以看作是静态路由的一种特殊情况。当数据在查找路由表时,没有找到和目标相匹配的路由表项时,为数据指定的路由。

四、实验步骤

实验拓扑

1、在路由器R1、R2上配置接口的IP地址和R1串口上的时钟频率;

2、查看路由器生成的直连路由;

3、在路由器R1、R2上配置静态路由;

4、验证R1、R2上的静态路由配置;

5、将PC1、PC2主机默认网关分别设置为与路由器接口f1/0 IP地址;

6、PC1、PC2主机之间可以互相通信;
