Layer 2 Vpn Architectures

A complete guide to understanding, designing, and deploying Layer 2 VPN technologies and pseudowire emulation applications Evaluate market drivers for Layer 2 VPNs Understand the architectural frame-work and choices for Layer 2 VPNs, including AToM and L2TPv3 Grasp the essentials of Layer 2 LAN and WAN technologies Examine the theoretical and operational details of MPLS and LDP as they pertain to AToM Understand the theoretical and operational details of Layer 2 protocols over L2TPv3 in IP networks Learn about Layer 2 VPN bridged and routed interworking and Layer 2 local switching Understand the operation and application of Virtual Private LAN Services (VPLS) Learn about foundation and advanced AToM and L2TPv3 topics through an extensive collection of case studies The historical disconnect between legacy Layer 2 and Layer 3 VPN solutions has forced service providers to build, operate, and maintain separate infrastructures to accommodate various VPN access technologies. This costly proposition, however, is no longer necessary. As part of its new Unified VPN Suite, Cisco Systems® now offers next-generation Layer 2 VPN services like Layer 2 Tunneling Protocol version 3 (L2TPv3) and Any Transport over MPLS (AToM) that enable service providers to offer Frame Relay, ATM, Ethernet, and leased-line services over a common IP/MPLS core network. By unifying multiple network layers and providing an integrated set of software services and management tools over this infrastructure, the Cisco® Layer 2 VPN solution enables established carriers, IP-oriented ISP/CLECs, and large enterprise customers (LECs) to reach a broader set of potential VPN customers and offer truly global VPNs. Layer 2 VPN Architectures is a comprehensive guide to consolidating network infrastructures and extending VPN services. The book opens by discussing Layer 2 VPN applications utilizing both AToM and L2TPv3 protocols and comparing Layer 3 versus Layer 2 provider-provisioned VPNs. In addition to describing the concepts related to Layer 2 VPNs, this book provides an extensive collection of case studies that show you how these technologies and architectures work. The case studies include both AToM and L2TPv3 and reveal real-world service provider and enterprise design problems and solutions with hands-on configuration examples and implementation details. The case studies include all Layer 2 technologies transported using AToM and L2TPv3 pseudowires, including Ethernet, Ethernet VLAN, HDLC, PPP, Frame Relay, ATM AAL5 and ATM cells, and advanced topics relevant to Layer 2 VPN deployment, such as QoS and scalability.

Master the latest MPLS VPN solutions to design, deploy, and troubleshoot advanced or large-scale networks With MPLS and VPN Architectures, Volume II, you'll learn: How to integrate various remote access technologies into the backbone providing VPN service to many different types of customers The new PE-CE routing options as well as other advanced features, including per-VPN Network Address Translation (PE-NAT) How VRFs can be extended into a customer site to provide separation inside the customer network The latest MPLS VPN security features and designs aimed at protecting the MPLS VPN backbone How to carry customer multicast traffic inside a VPN The latest inter-carrier enhancements to allow for easier and more scalable deployment of inter-carrier MPLS VPN services Advanced troubleshooting techniques including router outputs to ensure high availability MPLS and VPN Architectures, Volume II, builds on the best-selling MPLS and VPN Architectures, Volume I (1-58705-002-1), from Cisco Press. Extending into more advanced topics and deployment architectures, Volume II provides readers with the necessary tools they need to deploy and maintain a secure, highly available VPN. MPLS and VPN Architectures, Volume II, begins with a brief refresher of the MPLS VPN Architecture. Part II describes advanced MPLS VPN connectivity including the integration of service provider access technologies (dial, DSL, cable, Ethernet) and a variety of routing protocols (IS-IS, EIGRP, and OSPF), arming the reader with the knowledge of how to integrate these features into the VPN backbone. Part III details advanced deployment issues including security, outlining the necessary steps the service provider must take to protect the backbone and any attached VPN sites, and also detailing the latest security features to allow more advanced topologies and filtering. This part also covers multi-carrier MPLS VPN deployments. Finally, Part IV provides a methodology for advanced MPLS VPN troubleshooting. MPLS and VPN Architectures, Volume II, also introduces the latest advances in customer integration, security, and troubleshooting features essential to providing the advanced services based on MPLS VPN technology in a secure and scalable way. This book is part of the Networking Technology Series from Cisco Press(r), which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.

This revised version of the bestselling first edition provides a self-study complement to the Cisco CCIP training course implementing Cisco MPLS. Extensive case studies guide readers through the design and deployment of real-world MPLS/VPN networks MPLS and VPN Architectures.

A guide to designing and implementing VPLS services over an IP/MPLS switched service provider backbone Today's communication providers are looking for convenience, simplicity, and flexible bandwidth across wide area networks-but with the quality of service and control that is critical for business networking applications like video, voice and data. Carrier Ethernet VPN services based on VPLS makes this a reality. Virtual Private LAN Service (VPLS) is a pseudowire (PW) based, multipoint-to-multipoint layer 2 Ethernet VPN service provided by services providers By deploying a VPLS service to customers, the operator can focus on providing high throughput, highly available Ethernet bridging services and leave the layer 3 routing decision up to the customer. Virtual Private LAN Services (VPLS) is quickly becoming the number one choice for many enterprises and service providers to deploy data communication networks. Alcatel-Lucent VPLS solution enables service providers to offer enterprise customers the operational cost benefits of Ethernet with the predictable QoS characteristics of MPLS.

A comprehensive introduction to all facets of MPLS theory and practice Helps networking professionals choose the suitable MPLS application and design for their network Provides MPLS theory and relates to basic IOS configuration examples The Fundamentals Series from Cisco Press launches the basis to readers for understanding the purpose, application, and management of technologies MPLS has emerged as the new networking layer for service providers throughout the world. For many service providers and enterprises MPLS is a way of delivering new applications on their IP networks, while consolidating data and voice networks. MPLS has grown to be the new default network layer for service providers and is finding its way into enterprise networks as well. This book focuses on the building blocks of MPLS (architecture, forwarding packets, LDP, MPLS and QoS, CEF, etc.). This book also reviews the different MPLS applications (MPLS VPN, MPLS Traffic Engineering, Carrying IPv6 over MPLS, AToM, VPLS, MPLS OAM etc.). You will get a comprehensive overview of all the aspects of MPLS, including the building blocks, its applications, troubleshooting and a perspective on the future of MPLS.
