Selective QinQ configuration example (inner VLAN ID substitution)

As shown in Figure 68:

• Company A uses CVLAN 10 and CVLAN 20 to transmit voice traffic and data traffic separately, and Company B uses CVLAN 30 and CVLAN 40 to transmit voice traffic and data traffic separately. The services of the two companies are integrated together.

• 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 the edge and third-party devices to allow the voice traffic and data traffic to be transmitted between the two companies via SVLAN 100 SVLAN 200 separately.

	IMPORTANT: Make sure that you have configured the devices in the service provider network to allow QinQ packets to pass through.

1. Configure PE 1:

   • Configure GigabitEthernet 1/0/1:

     # Configure GigabitEthernet 1/0/1 as a hybrid port to permit frames of VLAN 100 and VLAN 200 to pass through untagged.

3. On the third-party devices between PE 1 and PE 2, configure the port that connects to PE 1 and that connecting to PE 2 to allow tagged frames of VLAN 100 and VLAN 200 to pass through. (Details not shown.)
