计网:实验三 综合性训练(搭建中小企业园区网)

实验三  综合性训练(搭建中小企业园区网)

  一、实验目的: 

1.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; 

2.通过路由建立起网络之间的连接,了解网络路由的设计与配置;

3.进一步熟悉交换机、路由器的基本操作命令。

二、实验设备:

计算机、二层交换机、路由器、外网服务器

三、实验拓扑图

 

 

 

四、实验过程:

步骤1:在4台交换机上创建vlan10/20/30,分别命名为yewubu,caiwubu,zonghebu 四台交换机:

Switch0

Switch>enable

Switch#config

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)#vlan 10

Switch(config-vlan)#name yewubu

Switch(config-vlan)#exit

Switch(config)#vlan 20

Switch(config-vlan)#name caiwubu

Switch(config-vlan)#exit
