要求：
- PC1和PC3所在接口为access；属于 vlan2；
PC2/4/5/6处于同一网段；其中PC2可以访问PC4/5/6;但PC4可以访问PC5，不能访问PC6- PC5不能访问PC6
- PC1/3与PC2/4/5/6不在同一个网段
- 所有PC通过DHCP获取IP地址,且PC1/3可以正常访问PC2/4/5/6
划分VLAN

使用DHCP分配IP
[R1]dhcp enable [R1]ip pool v1 [R1-ip-pool-v1]network 192.168.1.0 mask 255.255.255.0 [R1-ip-pool-v1]gateway-list 192.168.1.254 设置网关 [R1-ip-pool-v1]dns-list 114.114.114.114 设置DNS [R1-ip-pool-v1]q [R1]interface GigabitEthernet 0/0/0 [R1-GigabitEthernet0/0/0]ip address 192.168.1.254 24 [R1-GigabitEthernet0/0/0]dhcp select global [R1]ip pool v2 [R1-ip-pool-v2]network 192.168.2.0 mask 255.255.255.0 [R1-ip-pool-v2]gateway-list 192.168.2.2544 [R1-ip-pool-v2]dns-list 114.114.114.114 [R1-ip-pool-v2]q [R1]interface GigabitEthernet 0/0/0.2 [R1-GigabitEthernet0/0/0.2]ip address 192.168.2.254 24 设置IP地址 [R1-GigabitEthernet0/0/0.2]dot1q termination vid 2 定义子接口管理的VLAN [R1-GigabitEthernet0/0/0.2]dhcp select global 开启dhcp功能 [R1-GigabitEthernet0/0/0.2]arp broadcast enable 开启子接口arp广播应答功能，华为子接口默认不响应arp请求
查看ip
PC1
PC2
PC3
PC4
PC5
PC6
测试PC2可以访问PC4/5/6
[SW1]interface GigabitEthernet 0/0/3 [SW1-GigabitEthernet0/0/3]port hybrid untagged vlan all
测试PC4可以访问PC5，测试PC4不可以访问PC6
[SW3]interface GigabitEthernet 0/0/3 [SW3-GigabitEthernet0/0/3]port hybrid tagged vlan 4
PC5不能访问PC6
[SW3]interface GigabitEthernet 0/0/3 [SW3-GigabitEthernet0/0/3]port hybrid tagged vlan 5
且PC1/3可以正常访问PC2/4/5/6
