1、计算机网络课程设计1. 课程设计应达到的目的本课程设计的目的是使得学生在学习计算机网络这门课程的基础上，进一步理解计算机网络的基本理论，将理论知识和实践结合起来，提高学生的网络应用水平。课程设计是教学中很重要的一项实践环节，它可以帮助学生理解课堂教学中的内容，对提高学生的实践认识和实际动手能力都有很重要的实际意义。学生应按照课程设计的要求，结合所学的理论知识，查找相关资料，完成好本次课程设计任务，同时提高网络应用能力，为后续课程打好基础。2课程设计题目及要求题目：交换机与路由器互连综合设计要求：（1）按图 1 的要求连线：路由器之间的 V.35 线已连接好。必须连接的双绞线有：两台 PC 机与

2、网络设备的连线，交换机之间的连线，交换机 S3760 与路由器 RA 之间的连线。（2）配置交换机和路由器： S3750 中的端口使用 no switchport 命令升级为三层接口。 设计并配置交换机 S3760 和路由器 RA、RB 各接口的地址。 局域网中三层交换机 S3760、路由器 RA、路由器 RB 之间利用 RIP 动态路由协议实现网络互通。（3）配置 PC1 主机和 PC2 主机的 IP 地址和默认网关地址。（4）Ping 结果：在 pc1 中可以 ping 通全网中其他所有地址。（5）全网只使用网段 200.16.2.0/24 的地址。3、网络拓扑结构200.16.211/2
