Layer 2 VPNs


Cisco IOS® MPLS Bandwidth-Assured Layer 2 Services enables innovative services over an IP/MPLS infrastructure. This is a network architecture that provides enhanced MPLS Layer 2 functionality to drive network convergence by increasing resiliency with MPLS Fast Reroute (FRR) for AToM circuits, Quality of Service (QoS) guarantees using Differentiated Services (DiffServ), and better bandwidth utilization with MPLS Traffic Engineering (TE). Together these technologies emulate the traditional Layer 2 infrastructure and enable a smooth migration to an IP/MPLS network so you can use the new infrastructure to innovate and converge voice, video, data, storage services. This convergence increases your profit growth, simplifies your network management, and protects your investments with a standards-based, flexible architecture.

Enhancing Layer 2, Cisco IOS® MPLS Virtual Private LAN Service (VPLS) with Cisco® 7600 enables flexibility in deploying and managing innovative services. These services increase productivity and operational efficiencies by connecting geographically dispersed sites as one giant LAN over high-speed Ethernet in a robust and scalable IP/MPLS network.
