实验要求
- PC1和PC3接口都为 Access模式，VLAN2
- PC2-PC4-PC5-PC6都为同一个网段
- 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
实验规划
- 首先我们通过DHCP自动下放IP地址，可以在路由器上配置DHCP地址池，然后做DHCP中继
- SW1连接PC1和PC3的接口成正常的Access模式，创建并划入VLAN2
- PC2-PC4-PC5-PC6都在同一个网段，在同一个网段的话，通常情况下属于同一个VLAN，但是如果是同一个VLAN的话，难以实现PC4不能访问PC6，PC5不能访问PC6，那么此时需要多个VLAN来达成此要求，我们此时可以将PC2划入VLAN3，PC4划入VLAN2，PC5划入VLAN2，PC6划入VLAN3
- PC2：此时需定义SW1连接PC2的接口定义为Hybrid，Pvid改为VLAN 3，但是对于VLAN 2&3流量不打标记 untagged vlan 2 3，通过DHCP下放IP地址
- PC4：定义SW2连接PC4的接口定义为Hybrid，Pvid改为vlan 2，对于VLAN 2 & 3流量不打标记 untagged vlan 2 3，而PC4手动配置IP地址，虽然为VLAN 2，但是我们可以手动配置同VLAN 3同网段的IP地址
- PC5：定义SW3连接PC5的接口为定义为Hybrid，Pvid改为vlan 2，对于VLAN 2&3 流量不打标记 untagged vlan 2 3，PC5手动配置IP地址，配置同VLAN3同网段的IP地址
- PC6：定义SW3连接PC6的接口定义为Hybrid，Pvid为vlan 2，但是只对于VLAN 3的流量不打标记，untagged vlan 3，通过DHCP下IP地址
那么此时，这样规划之后
根据实验要求
- PC2-PC4-PC5-PC6处于同一个网段，达成
- PC2/4/5所在交换机接口模式都为Hybrid且都这对于VLAN 2/3流量都不打标记，此时可以正常通信，PC 6所在交换机接口为Hybrid，针对于VLAN 3流量不打标记，PC 2所在接口Pvid为vlan 3，此时PC2与PC6可以正常通信，达成
- PC4可以访问PC5，PC 4和PC 6不能通信，达成
- PC5和PC6不能通信，达成
