An Architecture for L2VPNs
Eric Wd Q, Eric Rosen, Clarence Filsfils · 2001
Providers may offer a Layer 2 VPN Service over an IP backbone by provisioning point-to-point that run through IP tunnels. This document discusses the signaling, encapsulation, and configuration issues that arise. Its purpose is to provide an architecture which allows different kinds of point-to- point virtual circuits to be provided through different kinds of IP tunnels.
