Layer 2 is also known as virtual private LAN service and is used to route video, audio and AMI traffic between data centres and sub-stations. Point-to-point, also known as pseudowire, uses virtual leased lines to provide point-to-point connectivity from one site to another. Layer 3 VPNs helps service providers participate in Layer 3 routing of customers.
