Book Description

Publication Date: March 20, 2005

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.

5.0 out of 5 stars Layer 2 VPN Architectures, May 24, 2005

This review is from: Layer 2 VPN Architectures (Hardcover)

For any person involved with designing or maintaining L2 VPNS "Layer 2 VPN Architectures" is a must. While I must admit that I use most of my books as reference, this book is an easy read for those persons who are trying to learn the various L2 VPNS options available. The book begins with a background of VPN architectures and follows with a background and overview of the different Layer 2 protocols. An in depth discussion of AtoM, Anything over MPLS, L2TPv3 and VPLS are presented to the reader.

The authors use case studies to fully explain the technology to the reader. Each case study builds on the other making for a very logical flow of each technology, including configuration examples and screen shots for a clearer explanation. The configuration examples and illustrations are numerous making this a great reference book as well as a learning tool.

Each of the three parts starts with a basic configuration and then slowly builds to a more complex example. As mentioned, the screen shots and the configuration snippets make it very easy to go from one case study to the next. The authors go to great links to explain all the command options and parameters. This assists the reader in obtaining a clearer understanding of the objective.

For the discussions on AToM and L2TPv3 the authors include the LAN and WAN protocols that can be transported over the two technologies. They give the reader an in-depth understanding of the command options available as well as why they should be used.

As a Cisco instructor this book has been very valuable in adding to the Service Provider oriented classes I teach. Anyone involved with MetroEthernet should read this book, as it will present all the technological options available. It will also help them in tuning their network. If you have aspirations on achieving a CCIE in the Service Provider space this book is a definite read for the Service Provider MES Written.

Overall I would rate this book a 5. I have a bookshelf full of Cisco Press books and this is one of the better ones I have.
