一、实验目标

  • 掌握OSPF协议的配置方法;
  • 掌握查看通过动态路由协议OSPF学习产生的路由;
  • 熟悉广域网线缆的连接方式;

二、实验背景

假设某公司通过一台三层交换机连到公司出口路由器上,路由器再和公司外的另一台路由器连接。现要做适当配置,实现公司内部主机与公司外部主机之间的相互通信。为了简化网管的管理维护工作,公司决定采用OSPF协议实现互通。

三、技术原理

OSPF开放式最短路径优先协议,是目前网络中应用最广泛的路由协议之一。属于内部网关路由协议,能够适应各种规模的网络环境,是典型的链路状态协议。OSPF路由协议通过向全网扩散设备的链路状态信息,使网络中每台设备最终同步一个具有全网链路状态的数据库,然后路由器采用SPF算法,以自己为根,计算到达其他网络的最短路径,最终形成全网路由信息。

四、实验步骤

实验拓扑

1、在三层交换机上划分VLAN10和VLAN20,其中VLAN10用于连接校园网主机,VLAN20用于连接R1;

2、路由器之间通过V.35电缆通过串口连接,DCE端连接在R1上,配置其时间频率为64000;

3、主机和交换机通过直连线连接,主机与路由器通过交叉线连接;

4、在S3560上配置OSPF路由协议;

5、在路由器R1、R2上配置OSPF路由协议;

6、将PC1、PC2主机默认网关分别设置为与直连网络设备接口IP地址;

7、验证PC1、PC2主机之间可以互相通信;
