VLAN transparent transmission configuration example

Network requirements

As shown in Figure 54:

• The two branches of a company, Site 1 and Site 2, are connected through the service provider

network and use VLANs 10 through 50.

• PE 1 and PE 2 are edge devices on the service provider network and are connected through

third-party devices with a TPID value of 0x8200.

Configure edge and third-party devices to allow frames of VLANs 10 through 50 to be transmitted

between branches of the company through the service provider network with no outer VLAN tags added.

Configuration procedure

IMPORTANT:

Make sure that you have confi

ured devices in the service provider network to allow QinQ packets to pass

through.

1. Configure PE 1:

a. Configure GigabitEthernet 4/0/1:

# Configure GigabitEthernet 4/0/1 as a trunk port and assign it to VLANs 10 through 50.

<PE1> system-view

[PE1] interface GigabitEthernet 4/0/1

[PE1-GigabitEthernet4/0/1] port link-type trunk

[PE1-GigabitEthernet4/0/1] port trunk permit vlan 10 to 50

# Enable basic QinQ on the port.

[PE1-GigabitEthernet4/0/1] qinq enable

# Configure the port to transparently transmit frames from VLANs 10 through 50.

[PE1-GigabitEthernet4/0/1] qinq transparent-vlan 10 to 50

[PE1-GigabitEthernet4/0/1] quit

b. Configure GigabitEthernet 4/0/2:

# Configure GigabitEthernet 4/0/2 as a trunk port and assign it to VLANs 10 through 50.
