GEC.
This feature enables service providers to supply connectivity between customer sites having data link
layer (Layer 2) networks, by using a single, integrated, packet-based network infrastructure—a Cisco
MPLS network. Instead of separate networks with separate network management environments, service
providers can deliver Layer 2 connections over an MPLS backbone.
