一、实验拓扑

二、实验需求

1.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;
2.PC5不能访问PC6;
3.PC1/3与PC2/4/5/6不在同一网段；
4.所有PC通过DHCP获取IP地址，且PC1/3可以正常访问PC2/4/5/6

三、实验思路

1.在交换机上配置VLAN并修改为对应接口

2.在路由器上配置网关

3.开启接口识别vid的功能配置对应vlan，且开启ARP广播

4.开启DHCP服务，配置地址池，下发地址

四、实验步骤

1.配置VLAN

[SW1]int g0/0/1
[SW1-GigabitEthernet0/0/1]port link-type access 
[SW1-GigabitEthernet0/0/1]port default vlan 2
[SW1-GigabitEthernet0/0/1]int g0/0/2
[SW1-GigabitEthernet0/0/2]port link-type hybrid
[SW1-GigabitEthernet0/0/2]port hybrid untagged vlan 2 3 4 5 6
[SW1-GigabitEthernet0/0/2]port hybrid pvid vlan 3
[SW1-GigabitEthernet0/0/2]int g0/0/3
[SW1-GigabitEthernet0/0/3]port link-type trunk
[SW1-GigabitEthernet0/0/3]port trunk allow-pass vlan 2 3 4 5 6
[SW1-GigabitEthernet0/0/3]int g0/0/4
[SW1-GigabitEthernet0/0/4]port link-type trunk 
[SW1-GigabitEthernet0/0/4]port trunk allow-pass vlan 2 3 4 5 6

[SW2]vlan batch 2 to 6
[SW2]int g0/0/1
[SW2-GigabitEthernet0/0/1]port link-type access 
[SW2-GigabitEthernet0/0/1]port default vlan 2
[SW2-GigabitEthernet0/0/1]int g0/0/2
[SW2-GigabitEthernet0/0/2]port link-type hybrid 
[SW2-GigabitEthernet0/0/2]port hybrid untagged vlan 2 3 5 6
[SW2-GigabitEthernet0/0/2]port hybrid tagged vlan 4
[SW2-GigabitEthernet0/0/2]port hybrid pvid vlan 3
[SW2-GigabitEthernet0/0/2]int g0/0/3
[SW2-GigabitEthernet0/0/3]port link-type trunk     
[SW2-GigabitEthernet0/0/3]port trunk allow-pass vlan 2 3 4 5 6
[SW2-GigabitEthernet0/0/3]int g0/0/4
[SW2-GigabitEthernet0/0/4]port link-type trunk
[SW2-GigabitEthernet0/0/4]port trunk allow-pass vlan 2 3 4 5 6

[SW3]vlan batch 2 to 6
[SW3]int g0/0/1
[SW3-GigabitEthernet0/0/1]port link-type hybrid 
[SW3-GigabitEthernet0/0/1]port hybrid untagged vlan 2
[SW3-GigabitEthernet0/0/1]port hybrid pvid vlan 3
[SW3-GigabitEthernet0/0/1]port hybrid tagged vlan 5
[SW3-GigabitEthernet0/0/1]int g0/0/2
[SW3-GigabitEthernet0/0/2]port link-type hybrid
[SW3-GigabitEthernet0/0/2]port hybrid untagged vlan 2
[SW3-GigabitEthernet0/0/2]port hybrid tagged vlan 6
[SW3-GigabitEthernet0/0/2]port hybrid pvid vlan 3
[SW3-GigabitEthernet0/0/2]int g0/0/3
[SW3-GigabitEthernet0/0/3]port link-type trunk
[SW3-GigabitEthernet0/0/3]port trunk allow-pass vlan 2 3 4 5 6

2.使用路由器子接口完成不同VLAN之间的通信

[R1]int g0/0/0.1
[R1-GigabitEthernet0/0/0.1]ip add 192.168.1.254 24
[R1-GigabitEthernet0/0/0.1]dot1q termination vid 2
[R1-GigabitEthernet0/0/0.1]arp broadcast enable 
[R1-GigabitEthernet0/0/0.1]int g0/0/0.2
[R1-GigabitEthernet0/0/0.2]ip add 192.168.2.254 24
[R1-GigabitEthernet0/0/0.2]dot1q termination vid 3
[R1-GigabitEthernet0/0/0.2]arp broadcast enable

3.开启DHCP服务

[R1]dhcp enable 

4.配置地址池

[R1]ip pool a
[R1-ip-pool-a]network 192.168.1.0 mask 24
[R1-ip-pool-a]gateway-list 192.168.1.254
[R1-ip-pool-a]dns-list 114.114.114.114 8.8.8.8
[R1-ip-pool-a]q
[R1]ip pool b
[R1-ip-pool-b]network 192.168.2.0 mask 24
[R1-ip-pool-b]gateway-list 192.168.2.254
[R1-ip-pool-b]dns-list 114.114.114.114 8.8.8.8

5.在接口中应用DHCP服务

[R1]int g0/0/0.1    
[R1-GigabitEthernet0/0/0.1]dhcp select  global 
[R1-GigabitEthernet0/0/0.1]int g0/0/0.2
[R1-GigabitEthernet0/0/0.2]dhcp select global

五、测试

所有PC通过DHCP获取IP地址且可以访问

PC5不能访问PC6
