Configuring basic QinQ

Introduction

The following information uses an example to describe the basic QinQ configuration procedure.

Network configuration

As shown in Figure 1, Site 1 and Site 2 belong to the same company and access the service provider network through access switches CE 1 and CE 2. VLAN 2 is used for internal network services of the company, and VLAN 200 is used in the service provider network. Configure QinQ on PE A and PE B to transmit traffic between Site 1 and Site 2 over the service provider network.

Figure 1 Network diagram

 

Restrictions and guidelines

Before enabling QinQ on a port, specify the PVID tag as the SVLAN tag for packet encapsulation.

Procedure

Configuring CE 1

# Create VLAN 2.

<CE 1> system-view

[CE 1] vlan 2

[CE 1-vlan2] quit

# Specify GigabitEthernet 1/0/2 and GigabitEthernet 1/0/3 as access ports to allow packets from VLAN 2 to pass through.

[CE 1] interface range gigabitethernet 1/0/2 to gigabitethernet 1/0/3

[CE 1-if-range] port access vlan 2

[CE 1-if-range] quit

# Specify GigabitEthernet 1/0/1 as a trunk port to allow packets from VLAN 2 to pass through.

[CE 1] interface gigabitethernet 1/0/1

[CE 1-GigabitEthernet1/0/1] port link-type trunk

[CE 1-GigabitEthernet1/0/1] port trunk permit vlan 2

[CE 1-GigabitEthernet1/0/1] quit

Configuring CE 2

Configure CE 2 in the same way CE 1 is configured. (Details not shown.)

Configuring PE A

# Create VLAN 2 and VLAN 200.

<PE A> system-view

[PE A] vlan 2

[PE A-vlan2] quit

[PE A] vlan 200

[PE A-vlan200] quit

# Specify GigabitEthernet 1/0/1 as a trunk port to allow packets from VLAN 2 and VLAN 200 to pass through.

[PE A] interface gigabitethernet 1/0/1

[PE A-GigabitEthernet1/0/1] port link-type trunk

[PE A-GigabitEthernet1/0/1] port trunk permit vlan 2 200

# Specify the PVID as VLAN 200 for GigabitEthernet 1/0/1.

[PE A-GigabitEthernet1/0/1] port trunk pvid vlan 200

# Enable QinQ for GigabitEthernet 1/0/1.

[PE A-GigabitEthernet1/0/1] qinq enable

[PE A-GigabitEthernet1/0/1] quit

# Specify GigabitEthernet 1/0/2 as a trunk port to allow packets from VLAN 200 to pass through.

[PE A] interface gigabitethernet 1/0/2

[PE A-GigabitEthernet1/0/2] port link-type trunk

[PE A-GigabitEthernet1/0/2] port trunk permit vlan 200

[PE A-GigabitEthernet1/0/2] quit

Configuring PE B

Configure PE B in the same way PE A is configured. (Details not shown.)

Verifying the configuration

Verify that a PC at Site 1 and a PC at Site 2 can ping each other successfully and learn the MAC addresses from each other. CVLAN information can be transparently transmited between the two PCs over the service provider network.

# Ping a PC at Site 2 from a PC at Site 1 to verify the connectivity.

C:\Users\usera>ping 192.168.1.2

 

Pinging 192.168.1.2 with 32 bytes of data:

Reply from 192.168.1.2: bytes=32 time=28ms TTL=253

Reply from 192.168.1.2: bytes =32 time =27ms TTL=253

Reply from 192.168.1.2: bytes =32 time =27ms TTL=253

Reply from 192.168.1.2: bytes =32 time =26ms TTL=253

 

Ping statistics for 192.168.1.2:

    Packets: Sent = 4, Received = 4, Lost = 0 (0% Loss),

Approximate round trip time in milli-seconds:

Minimum = 26ms, Maximum = 28ms, Average = 27ms

# View the MAC address table on CE 1 to verify that CE 1 has learned the MAC address of the PC at Site 2.
