Network requirements
As shown in
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.
