一份网络专业毕业设计

设计目标： 组建可扩展的局域网和广域（内联）网

用户需求 ：

某学校由新校区和老校区组成。新校区由办公楼和教学楼（楼层均为三层）组成，办公楼与教学楼之间距离为300米；老校区由办公楼和教学楼组成。

新校区：要求组建内部局域网。办公楼一层有15个信息点，办公楼二层有16个信息点，办公楼三层有20个信息点；教学楼一层有17个信息点，教学楼二层有12个信息点，教学楼三层有18个信息点。核心交换机安装在网络中心，位于办公楼二层。办公楼汇聚交换机也位于核心机房，教学楼汇聚机房位于二层。要求在教学楼汇聚交换机上划分如下VLAN：教学楼一层要求划分2个VLAN，分别给教室和办公室使用，教学楼二层划分3个VLAN，分别给教室、实验室和办公室使用，教学楼三层划分1个VLAN，给教室使用。即教学楼共需6个业务VLAN，每层的教室、实验室和办公室的计算机如果出现病毒引发大量广播，不会传播到其它的楼层。

核心层设备与汇聚层设备之间使用路由协议互联，既可以使用静态路由、也可以使用动态路由。

如果机器性能允许运行9台Dynamips虚拟机（至少需要1G内存），则可以将办公楼的汇聚层交换机和接入层交换机也设计进网络中，（即实现局域网网络规模的扩展）办公楼每层划分1个VLAN，共3个业务VLAN。

老校区：暂不要求划分VLAN，能和新校区连通就可以。

新老校之间使用电信租用DDN线路互联，组成一个Intranet。（如果将来还有其他校区，也能够与现在的新校区实现互联，实现内联网网络规模的扩展。）

要求新校办公楼二层核心设备、教学楼一层、二层、三层和老校的所有联网计算机都可以互相通信。

 

核心交换机上联一台防火墙，防火墙采用城域网专线接入Internet，防火墙的内口地址为192.168.0.1/30，要求所有机器都能ping通此接口地址。（不要求配置防火墙，也不要求配置NAT）

设计要求：

需求分析（详述用户网络组建需求）

拓扑图（全网拓扑，使用 Visio 等 绘制）

逻辑设计（网络互联方法、 VLAN 划分、路由协议选择等）

地址规划（合理规划 IP 地址分配）

设备选型（可使用各厂商的网络设备）

s5 s6 配置与s4类似此处省略
R1 R2 只需配置好每个端口ip然后配置ospf协议，端口ip和路由协议配置与核心交换机类似此处省略。

 总结

1.题目要求可扩展的局域网组建

实验过程用了vtp

vtp是思科私有协议，若扩展使用别的厂商设备如华为就达不到可扩展性的要求

其实完全可以自己手工划分下vlan，使用vtp只是为了方便

2.使用三层交换的时候记得两条条命令

ip routing

和no shut

我在配置了ospf协议后彼此之间学习不到路由信息

郁闷了半天才发现忘了ip routing 来启用三层交换的路由功能
