A. Peer-to-peer VPNs require the establishment of virtual circuits to connect the different customer sites together.
B. Peer-to-peer VPNs require the service provider to participate in the customer routing, accepting customer routes, transporting them across the service provider backbone, and finally propagating them to other customer sites.
C. With peer-to-peer VPNs, the service provider is responsible for transport of Layer 2 frames between customer sites, and the customer takes responsibility for all higher layers.
D. The implementation of Layer 2 overlay VPNs is the traditional switched-WAN model, implemented with technologies like X.25, Frame Relay or ATM.
E. With Layer 2 overlay VPNs, the service provider is not aware of customer routing and has no information about customer routes.
