灵活QinQ配置

拓扑

实验思路

①SWA：

创建私网vlan

连接PC的口使用access口；连接PE使用trunk口放行私网vlan

②PE：

创建公网、私网vlan

连接SWA的口使用bybrid口；tagged放行私网vlan，untagged放行公网vlan

连接SWA的口做vlan mapping 映射公网与私网的对应

连接P的口使用trunk口，放行公网vlan

③P：

创建公网vlan

所有接口设置为trunk，放行公网vlan

实验步骤

一、配置PC的IP地址，修改设备名

略

二、SWA配置

[SWA]v 5  6

[SWA]v 5

[SWA-vlan5]port g1/0/2

[SWA-vlan5]v 6

[SWA-vlan6]port g1/0/3

[SWA-vlan6]int g1/0/1

[SWA-GigabitEthernet1/0/1]p l t

[SWA-GigabitEthernet1/0/1]port trunk permit vlan 5  6

三、PE1配置

[PE1]v 5 6 100 200

[PE1]int g1/0/1

[PE1-GigabitEthernet1/0/1]port link-type hybrid

[PE1-GigabitEthernet1/0/1]port hybrid vlan 5 6 tagged

[PE1-GigabitEthernet1/0/1]port hybrid vlan 100 200 untagged

[PE1-GigabitEthernet1/0/1]vlan mapping nest single 5 nested-vlan 100

[PE1-GigabitEthernet1/0/1]vlan mapping nest single 6 nested-vlan 200

[PE1-GigabitEthernet1/0/1]int g1/0/2

[PE1-GigabitEthernet1/0/2]p l t

[PE1-GigabitEthernet1/0/2]port trunk permit vlan 100 200

四、P配置

[P]v 100 200

[P]int g1/0/1

[P-GigabitEthernet1/0/1]p l t

[P-GigabitEthernet1/0/1]port trunk permit vlan 100 200

[P-GigabitEthernet1/0/1]int g1/0/2

[P-GigabitEthernet1/0/2]p l t

[P-GigabitEthernet1/0/2]port trunk permit vlan 100 200

五、PE2配置

[PW2]v 5 6 100 200

[PW2]int g1/0/1

[PW2-GigabitEthernet1/0/1]p l t

[PW2-GigabitEthernet1/0/1]port trunk permit vlan 100 200

[PW2-GigabitEthernet1/0/1]int g1/0/2

[PW2-GigabitEthernet1/0/2]p l h

[PW2-GigabitEthernet1/0/2]port hybrid vlan 5 6 tagged

[PW2-GigabitEthernet1/0/2]port hybrid vlan  100 200 untagged

[PW2-GigabitEthernet1/0/2]vlan mapping nest single 5 nested-vlan 100

[PW2-GigabitEthernet1/0/2]vlan mapping nest single 6 nested-vlan 200

六、SWB配置

[SWB]v 5 6

[SWB]v 5

[SWB-vlan5]port g1/0/2

[SWB-vlan5]v 6

[SWB-vlan6]port g1/0/3

[SWB-vlan6]int g1/0/1

[SWB-GigabitEthernet1/0/1]p l t

[SWB-GigabitEthernet1/0/1]port trunk permit vlan 5  6

测试：

1、PC1 ping PC3，并在公网链路上抓包
