二、实验步骤

1、启用 VLAN

sw1上创建VLAN2~5

[sw1]vlan batch 2 to 5

接口配置

pc1接口

[sw1]int e0/0/1
[sw1-Ethernet0/0/1]port link-type access 
[sw1-Ethernet0/0/1]port default vlan 2

此时pc1的接口锁死在VLAN2（进出只能在VLAN2）且不打标签

pc2接口：

[sw1-Ethernet0/0/1]int e0/0/2
[sw1-Ethernet0/0/2]port hybrid untagged vlan 3 4 5
[sw1-Ethernet0/0/2]port hybrid untagged vlan 3
[sw1-Ethernet0/0/2]port hybrid pvid vlan 3

从下往上均会打上VLAN3的标签
从上往下允许VLAN3、4、5且不打标签

[sw1]int g0/0/2
[sw1-GigabitEthernet0/0/2]port hybrid tagged vlan 2 to 5

[sw2]vlan batch 2 to 5
[sw2]int g0/0/2
[sw2-GigabitEthernet0/0/2]port link-type trunk 
[sw2-GigabitEthernet0/0/2]port trunk allow-pass vlan 2 to 5

VLAN2~5打标签 VLAN1不打标签

[sw2]int e0/0/1
[sw2-Ethernet0/0/1]port link-type access 
[sw2-Ethernet0/0/1]port default vlan 2
[sw2-Ethernet0/0/1]int e0/0/2
[sw2-Ethernet0/0/2]port hybrid pvid vlan 4
[sw2-Ethernet0/0/2]port hybrid untagged vlan 3 to 4

[sw2]int g0/0/1
[sw2-GigabitEthernet0/0/1]port link-type trunk 
[sw2-GigabitEthernet0/0/1]port trunk allow-pass vlan 2 to 5

[sw3]vlan batch 2 to 5
[sw3]int g0/0/1
[sw3-GigabitEthernet0/0/1]port hybrid tagged vlan 2 to 5
[sw3-GigabitEthernet0/0/1]int e00/0/1
[sw3-Ethernet0/0/1]port hybrid pvid vlan 4
[sw3-Ethernet0/0/1]port hybrid untagged vlan 3 to 4
[sw3-Ethernet0/0/1]int e0/0/2
[sw3-Ethernet0/0/2]port hybrid pvid vlan 5
[sw3-Ethernet0/0/2]port hybrid untagged vlan 3 5

[sw1]int g0/0/1
[sw1-GigabitEthernet0/0/1]port hybrid tagged vlan 2
[sw1-GigabitEthernet0/0/1]port hybrid untagged vlan 3 to 5

从下往上VLAN2打标签 VLAN3~5不打标签

2、路由器配置

子接口

标 记 识 别 的 标 签
配 IP
开 启 ARP

[r1]int g0/0/0.1
[r1-GigabitEthernet0/0/0.1]dot1q termination vid 2
[r1-GigabitEthernet0/0/0.1]ip address 192.168.1.1 24
[r1-GigabitEthernet0/0/0.1]arp broadcast enable 

物理接口

配IP

[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]ip add 192.168.2.1 24

DHCP池塘（获取IP）

[r1]dhcp enable
[r1]ip pool v2
[r1-ip-pool-v2]network 192.168.1.0 mask 24
[r1-ip-pool-v2]gateway-list 192.168.1.1
[r1-ip-pool-v2]dns-list 114.114.114.114 8.8.8.8
[r1]ip pool v3
[r1-ip-pool-v3]network 192.168.2.0 mask 24
[r1-ip-pool-v3]gateway-list 192.168.2.1
[r1-ip-pool-v3]dns-list 114.114.114.114 8.8.8.8

[r1]interface g0/0/0
[r1-GigabitEthernet0/0/0]dhcp select global 
[r1-GigabitEthernet0/0/0]int g0/0/1
[r1-GigabitEthernet0/0/1]dhcp select global 

此时pc1~6能自动获取IP
