VLAN 实验

设置子接口与物理接口

[R1]interface g0/0/0.1
[R1-GigabitEthernet0/0/0.1]ip add 192.168.1.1 24
[R1-GigabitEthernet0/0/0.1]dot1q termination vid 2 #配置封装标准，从此接口进出时要封装vlan id
[R1-GigabitEthernet0/0/0.1]arp broadcast enable #开启子接口的arp广播功能
 
[R1]inter g0/0/0
[R1-GigabitEthernet0/0/0]ip add 192.168.2.1 24

配置DHCP服务

[R1]dhcp enable 
[R1]ip pool a
[R1-ip-pool-a]network 192.168.1.0 mask 24
[R1-ip-pool-a]gateway-list 192.168.1.1
[R1]ip pool b
[R1-ip-pool-a]network 192.168.2.0 mask 24
[R1-ip-pool-a]gateway-list 192.168.2.1
 
 [R1-GigabitEthernet0/0/0.1]dhcp select global
[R1-GigabitEthernet0/0/0]dhcp select global

创建所需的vlan

[SW1]vlan batch 2 to 6
[SW2]vlan batch 2 to 6

设置access接口

[SW1]inter g0/0/3
[SW1-GigabitEthernet0/0/3]port link-type access
[SW1-GigabitEthernet0/0/3]port default vlan 2
[SW1]inter g0/0/2
[SW1-GigabitEthernet0/0/2]port link-type access
[SW1-GigabitEthernet0/0/2]port default vlan 2

设置trunk干道

[SW1-GigabitEthernet0/0/6]port link-type trunk
[SW1-GigabitEthernet0/0/6]port trunk allow-pass vlan 3 5 to 6
 
[SW2-GigabitEthernet0/0/1]port link-type trunk 
[SW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 3 5 to 6

设置PC2\4\5\6的接入口

[SW1-GigabitEthernet0/0/4]port hybrid pvid vlan 3
[SW1-GigabitEthernet0/0/4]port hybrid untagged vlan 1 to 6
 
[SW1-GigabitEthernet0/0/5]port hybrid pvid vlan 4
[SW1-GigabitEthernet0/0/5]port hybrid untagged vlan 1 to 6

PC5除了不能被vlan4的PC4访问
[SW2-GigabitEthernet0/0/2]port hybrid untagged vlan 1 to 3 5 to 6

PC6不能被vlan4的PC4和vlan5的PC5访问
[SW2-GigabitEthernet0/0/3]port hybrid untagged vlan 1 to 3 6

设置SW1到R1的出接口

[SW1-GigabitEthernet0/0/1]port hybrid untagged vlan 1 3 to 6
[SW1-GigabitEthernet0/0/1]port hybrid tagged vlan 2

验证

PC2能ping通PC4\5\6
