YS-《计算机网络》上机任务书-PT实验三

1、计算机网络上机任务书实验三 网络互联之路由器配置实验目的：熟悉路由器工作原理练习 cisco 路由器端口的基本配置 掌握静态路由的配置 掌握动态路由协议的配置、实验任务 一）静态路由设置 二）动态路由 RIP 协议设置（二） *动态路由OSPf协议设置四） *路由器综合配置实验一）静态路由设置、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

2、进行相连，要求做适当配置实现两个校区间 的正常相互访问。、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、配置过

5、置时钟频率，P acket Tracer需要添加串口模块，然后用串行线相连，在 DCE端会显示一个很小的时钟，标明需要配置时钟频率。（以太网E 口 F 口都不 能配置时钟频率，只有S 口可以配置）2 2、配置步骤路由器R1R1配置：RouterRoutere nRouter#c onf tEn ter con figurati on comma nds, one per line.

25、三、技术原理RIP (Routing Information Protocols)，路由信息协议，是应用较早、使用较普通的 内部网关协议，适用于小型同类网络，是距离矢量协议；RIP协议以跳数衡量路径开销，RIP协议里规定最大跳数为15；RIP协议有两个版本：RIPV1和RIPV2，RIPV1属于有类路由协议，不支持IGP广播形式进行路由信息的更新，更新周期为30秒；RIPv2属于无类路由协议，支持以组播形式进行路由更新。VLSM，以VLSM ,四、实验过程1 1实验拓扑r c RIE2-昭込f扛济 -P 如命 pK. 16S.2.1flpci19Z.160. 1. 2/Z4102.
