软件学院综合性实验报告
专业 年级/班级：12级软件学院 20##—20##学年第学1期
一、实验目的
假设某校园网通过1台三层交换机连到校园网出口路由器，路由器再和校园外的另一台路由器相接，现做适当配置，实现校园网内部主机与校园网外部主机的相互通信。
通过对网络设备的连通和对拓扑的分析，加深对常见典型局域网拓扑的理解；通过路由建立起网络之间的连接，熟悉交换机、路由器的基本操作命令，了解网络路由的设计与配置。
二、实验仪器或设备
二层交换机五台、三层交换机一台， 路由器两台，学生实验主机五台及一台服务器。
三、总体设计（设计原理、设计方案及流程等）
1、三层交换机上划分VLAN2 VLAN3VLAN4 VLAN5 VLAN6并且配置DHCP。
2、物理学院、化学院最多分计算机有250台，生物政管学院最多有120台计算机和服务器，需要对生物和政管学院划分子网。
3、三层交换机和出口路由器Ri相连。
4、局域网内部三层交换机和路由器Ri间利用RIPv2实现全网互通。
5、pc0 pc1 pc2 pc3 pc4的ip地址动态获得，对pc5配置ip 172.16.1.2

（6）测试结果
用pc5ping pc0~pc4
六、结果分析与总结
1.做实验的过程的讲过的实验报告可以作为参考
2.实验比较复杂，细节比较多，做实验的时候有耐心；
3.对于不明白的地方应该及时请教老师或者同学；
4.由于是截图形式，打印出来效果会差一点；
5.做的过程中应该认真仔细，一个符号的错误就可能导致运行不出来；
6.最终结果自己也比较满意，也是对老师和自己交出的一个好成绩
