一，创建VLAN

[sw1]vlan batch 2 to 6
[sw2]vlan batch 2 to 6
[sw3]vlan batch 2 to 6

二，通过需求修改接口

SW1：
[sw1]int g0/0/2
[sw1-GigabitEthernet0/0/2]port link-type access   ---将接口设置为access
[sw1-GigabitEthernet0/0/2]port default vlan 2   ---将接口划入vlan 2
[sw1]int g0/0/3
[sw1-GigabitEthernet0/0/3]port link-type hybrid  ---将接口设置为hybrid（默认）
[sw1-GigabitEthernet0/0/3]port hybrid pvid vlan 3  ---修改pvid为3
[sw1-GigabitEthernet0/0/3]port hybrid untagged vlan 3 4 5 6  ---允许不带标签的帧通过vlan 3 4 5 6
[sw1]int g0/0/4
[sw1-GigabitEthernet0/0/4]port link-type trunk    ---将接口设置为trunk
[sw1-GigabitEthernet0/0/4]port trunk allow-pass vlan all   ---放空所有valn

SW2；
[sw2-GigabitEthernet0/0/2]port link-type access 
[sw2-GigabitEthernet0/0/2]port default vlan 2
[sw2-GigabitEthernet0/0/3]port hybrid pvid vlan 4    
[sw2-GigabitEthernet0/0/3]port hybrid untagged vlan 3 4 5
[sw2-GigabitEthernet0/0/1]port link-type trunk 
[sw2-GigabitEthernet0/0/1]port trunk allow-pass vlan all 
[sw2-GigabitEthernet0/0/4]port link-type trunk 
[sw2-GigabitEthernet0/0/4]port trunk allow-pass vlan all 

SW3：
[sw3]int g0/0/1
[sw3-GigabitEthernet0/0/1]port link-type trunk 
[sw3-GigabitEthernet0/0/1]port trunk allow-pass vlan all 
[sw3-GigabitEthernet0/0/2]port hybrid pvid vlan 5
[sw3-GigabitEthernet0/0/2]port hybrid untagged vlan 3 4 5
[sw3-GigabitEthernet0/0/3]port hybrid pvid vlan 6
[sw3-GigabitEthernet0/0/3]port hybrid untagged vlan 3

SW1：
[sw1]int g0/0/1
[sw1-GigabitEthernet0/0/1]port link-type hybrid 
[sw1-GigabitEthernet0/0/1]port hybrid untagged vlan 3 4 5 6
[sw1-GigabitEthernet0/0/1]port hybrid tagged vlan 2

三，创建单臂路由

[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]ip address 192.168.2.1 24
[r1-GigabitEthernet0/0/0]int g0/0/0.1
[r1-GigabitEthernet0/0/0.1]ip address 192.168.1.1 24
[r1-GigabitEthernet0/0/0.1]dot1q termination vid 2
[r1-GigabitEthernet0/0/0.1]arp broadcast enable 
分发IP地址
[r1]dhcp enable 
[r1-ip-pool-aa]network 192.168.1.0 mask 24
[r1-ip-pool-aa]gateway-list 192.168.1.1
[r1]int g0/0/0.1
[r1-GigabitEthernet0/0/0.1]dhcp select global 

[r1]ip pool bb
[r1-ip-pool-bb]network 192.168.2.0 mask 24
[r1-ip-pool-bb]gateway-list 192.168.2.1
[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]dhcp select global
