实验拓补图
实验分析
一、实验目的
- 掌握VLAN的创建和配置方法
- 理解VLAN在局域网中的作用
- 学习如何通过VLAN实现网络隔离和通信
二、实验环境
- 交换机（SW1、SW2、SW3）
- 个人电脑（PC1、PC2、PC3、PC4、PC5、PC6）
- 路由器（R1）
- 网络连接线
四、实验需求
- PC1和PC3所在接口为access接口，属于VLAN 2
- PC2/4/5/6处于同一网段，其中PC2可以访问PC4/5/6，PC4可以访问PC5不能访问PC6，PC5不能访问PC6
- PC1/3和PC2/4/5/6不在一个网段，且可以正常通讯
- 所有PC通过DHCP获取IP地址，且PC1/3可以正常访问PC2/4/5/6
五、实验步骤和配置
-
创建VLAN
- 在SW1、SW2、SW3上创建VLAN 2、3、4、5、6
-
配置接口
- SW1、SW2、SW3的接口配置如下：
- PC1和PC3的接口配置为access接口，属于VLAN 2
- PC2、PC4、PC5、PC6的接口配置为hybrid接口，分别属于VLAN 3、4、5、6
- SW1、SW2、SW3的接口配置如下：
-
配置DHCP服务
- 在R1上配置DHCP服务，创建两个地址池，分别为PC1/3和PC2/4/5/6分配IP地址
-
测试连通性
- 测试PC1、PC3可以正常访问PC2、PC4、PC5、PC6
- 测试PC2可以访问PC4、PC5、PC6
- 测试PC4可以访问PC5，不能访问PC6
- 测试PC5不能访问PC6
六、实验结果
- 所有PC均通过DHCP获取到IP地址
- PC1、PC3可以正常访问PC2、PC4、PC5、PC6
- PC2可以访问PC4、PC5、PC6
- PC4可以访问PC5，不能访问PC6
- PC5不能访问PC6
