小型校园网的设计与组建试验报告

1、A'小型校园网的设计与组建实验报告一实验目的计算机网络是一门实践性较强的技术，课堂教学应该和实践环节紧密结合。 计算机网络实验培养学生具有独立进行计算机网络架构和设计能力， 提高学生的 网络设备使用水平，以及将理论与实践相结合的能力。二实验环境及设备2台路由器、2台交换机、3台PC机三实验的内容和要求根据要求， 设计并搭建一个校园网。 要求进行子网划分和结构设计， 并将网 络结构建立起来。最后完成网络设备的调试。四实验说明 某大学分为总校和分校，为该校设计校园网，总校有一个局域网共 20 台计 算机，分校由VLAN划分为两个局域网，分别有10台计算机。该校被分配了一 个C类网段210.

2、100.10.0,总校和分校各有一台路由器及一台交换机。请进行网 络设计，将总校和分校各个局域网连接起来。根据要求，设计 IP 地址分配表，设计网络结构，画出网络拓扑图。根据设 计搭建网络结构。配置网络设备，完成网络调试。提示：1）使用IP子网掩码的原理设计IP地址分配表。2）用到的设备为两台路由器，以及两台交换机。五实验设计一、 设计思路总校局域网 20台计算机，分校 2个局域网各有 1 0台计算机，若要满足要求， 则至少需要5位主机位，即大小为2八5=32台主机的局域网。由于是C类网段， 最后 8 计算机 ID 码 5 位用作主机号，还有 3 位可以用作子网号，即可以划分 2A3-2=6个

3、子网（000和111不可用作子网号），因此子网掩码为255.255.255.224(1111 1111.1111 1111.1111 1111.1110 0000。而总校、分校各个局域网只需从6个子网中任选其一并且不重复即可。由此可以设计IP分配表如下IP分配表用途网段网络号子网掩码子网号起始IP地址结束IP地址总校网1210.100.10.32255.255.255.224001210.100.10.33210.100.10.62路由器间2210.100.10.64255.255.255.224010210.100.10.65210.100.10.94分校网13210.100.10.9625
