一、题目要求
1、PC1和pc3所在接口为Access接口，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，但不能访问PC6，PC5不能访问PC6；
2、PC1/3与PC2/4/5/6不在同一网段；
3、所有PC通过DHCP获取IP地址，且PC1/3可以正常访问PC2/4/5/6。
注：所示拓扑图中PC5,PC6名称错误，正确拓扑图在拓扑结构中。
二、题目分析
1.网段划分
192.168.1.0 24–PC1/3
192.168.2.0 24–PC2456
2.vlan划分
PC1，3–vlan2
PC2–vlan3
PC4–valn4
PC5–vlan5
PC6–vlan6
3.接口分析
PC1/3为access
PC2/4/5/6为hybird
sw1-g0/0/4为hybird
交换机之间为trunk
4.DHCP
在R1配置子接口，属于VLAN2
5.阻塞分析
PC1/2/3正常访问
PC4->PC1/2/3/5，U:2345
PC5->PC1/2/3/4，U:2345
PC6->PC1/2/3，U:236
三、拓扑结构
拓扑结构如图所示
四、基本配置
所有PC启用DHCP(同PC1):
