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 100 and VLAN 200 to pass through.

Network requirements
As shown in Figure 60 :
• The two branches of a company, Site 1 and Site 2, are connected through the service provider
network and uses 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 the edge and third-party devices to allow frames of VLANs 10 through 50 to be
transmitted between the branches of the company via the service provider network with no outer
VLAN tags added.
