  DynamipsGUI前身源于美国加利福尼亚一黑客的杰作，为此CISCO也是相当的不爽，当然这是后话了。后被小凡编写成为中国CISCO学习者，考CCNA、NP、IE必备的模拟软件，为大家省去了不少银子。
 
  好了不多说，下面我就来介绍DynamipsGUI 2.7的使用方法。
 
 
1
 

 
在图一中：
1：是有关路由、交换个数，型号等相关设置，依据试验要求设置不多做说明
2：
IOS文件：相关交换机、路由型号的镜像文件，须从网上下载（如下图）

IDLE-PC值：通过计算得出，如不计算，CPU利用率会轻松达到100%(如何计算在下面详细介绍）
 
3：
在DynamipsGUI目录下，新建一个子目录，此目录做放模拟器用
注：最好别用中文名
 
 
 
2

 
按CTRL+]+I取得idle-pc值，取数字最大的

实验工具：在虚拟机中完成，3台CISCO7200路由，2台3640交换，6台PC
实验要求：同时设置RIP、VLAN、Trunk、单臂路由
实验目的：不同网段的6台PC能相互PING通
 
动态路由RIP：能通过计算，适应网络结构变化，而不像静态路由要通过管理员修改其跳数。

三个路由全都设置好后的情况，如果只设置了一个后SHOW，由于没有学习到别的路由的网段，不会出现一下信息。

实验工具：模拟CISO3640交换机2台，PC6台
 
实验目的：设置Trunk后，同一VLAN的PC能PING通
 
VLAN：对网络用户逻辑分段，不受位置限制。也就是说同一VLAN可PING通，不同不能通。
 
Trunk(中继):用一条物理链路将一台交换机连接其他交换机或路由

实验工具：在模拟器中完成CISCO7200路由三台，PC2台
实验目的：PC1能PING同PC2
 
静态路由：由于需要管理员手动设置，除非管理员干预，静态路由不会发生变化。所以只适用与小型固定的拓扑结构

默认路由：设置默认路由能提高网络性能，一般用于末梢网络，也就是只有一个唯一的路径能够达到的网络。
