3. Configure third-party devices.
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 10 through VLAN 50 to pass through.

Network requirements
As shown in Figure 61 :
• The two branches of a company, Site 1 and Site 2, are connected through the service provider
network and use CVLAN 10 and CVLAN 20 to transmit voice traffic and data traffic separately.
• 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 frames from CVLAN 10 to be transmitted
between the branches via SVLAN 100 and frames from CVLAN 20 to be transmitted between the
branches via SVLAN 200.

Configuration procedure
NOTE:
Be sure that you have configured the switches 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.
