IPv6 for Enterprise Networks brings together all the information you need to successfully deploy IPv6 in any campus, WAN/branch, data center, or virtualized environment. Four leading Cisco IPv6 experts present a practical approach to organizing and executing your large-scale IPv6 implementation. They show how IPv6 affects existing network designs, describe common IPv4/IPv6 coexistence mechanisms, guide you in planning, and present validated configuration examples for building labs, pilots, and production networks.
The authors first review some of the drivers behind the acceleration of IPv6 deployment in the enterprise. Next, they introduce powerful new IPv6 services for routing, QoS, multicast, and management, comparing them with familiar IPv4 features and behavior. Finally, they translate IPv6 concepts into usable configurations. Up-to-date and practical, IPv6 for Enterprise Networks is an indispensable resource for every network engineer, architect, manager, and consultant who must evaluate, plan, migrate to, or manage IPv6 networks.

About the Author
Shannon McFarland, CCIE No. 5245, is a corporate consulting engineer for Cisco, working as a technical
consultant for enterprise IPv6 deployment and data center design with a focus on application deployment
and virtual desktop infrastructure. Over the last 16 years, he has worked on large-scale enterprise campus
and WAN/branch network design, data center design and optimization for Microsoft operating systems
and server applications, as well as design and optimization of virtual desktop infrastructure deployments.
For the past 10 years, Shannon has been a frequent speaker at IPv6 events worldwide (notably Cisco Live
[formerly Networkers]), IPv6 summits, and other industry events. He has authored many papers and Cisco
Validated Designs (CVD) on IPv6, IP Multicast, Microsoft Exchange, VMware View, and other applications,
as well as contributed to many Cisco Press books. Prior to his time at Cisco, Shannon worked as a
consultant for a value-added reseller and also as a network engineer in the healthcare industry. Shannon
lives with his wife and children in Castle Rock, CO.
Muninder Sambi, CCIE No. 13915, is a manager of product marketing for the Cisco Catalyst 4500/4900
series platform. As a product line manager, he is responsible for defining product strategies on the multibillion-
dollar Catalyst 4500 and 4900 series platforms, which include next-generation product architectures
both for user access in Campus and Server access in the Data Center. Prior to this role, Muninder
played a key role in defining the long-term Software and Services strategy for Cisco’s modular switching
platforms (Catalyst 6500 and 4500/4900 series) including a focus on IPv6 innovations. Some of these
innovations enabled dual-stack IPv6 deployments in large enterprise and service provider networks.
Muninder is also a core member of Cisco’s IPv6 development council. Muninder has represented Cisco as
part of multiple network design architecture reviews with large enterprise customers. Over the last 12+
years, Muninder has worked on multiple Enterprise Campus, WAN, and Data Center designs. Prior to
working at Cisco, Muninder worked as a network consultant for one of India’s leading network integrators
and was responsible for designing and implementing LAN, WAN, and hosted Data Center networks.
Muninder lives with his wife and children in Fremont, California.
Nikhil Sharma, CCIE No. 21273, is a technical marketing engineer at Cisco, where he is responsible for
defining new features, both hardware and software, for the Catalyst 4500 product line. Over the last 10
years, Nikhil has worked with various enterprise customers to design and troubleshoot both large and
midsize campus and data center networks.

Most Helpful Customer Reviews
IP version 6 is the rave of the networking community today; with the first ever IP version 6 day set for June 8, 2011 ; the "official" depletion of IP version 4 addresses in Winter of 2011 and the increasing number of mandates (US Department of Defence June 9, 2003 memo). The need for a simple, concise, yet largely complete IP v6 design guide is becoming more pressing. IP version 6 for Enterpris Networks by Shannon McFarland and co seeks to fill that niche. It is not an IP v6 tutorial and should not be used as a reference guide for Internet Protocol, of any version. What it is however, is a well crafted IP v6 design consultant in a book. Organized into twelve chapters of just over 360 pages, the book is a light read, but heavy in design narrative that will help network managers, network architects and network design engineers chart a consistent and holistic framework to fit their specific network environment, and perhaps design a robust, scalable and resilient IP v6 architecture. The first chapter of the book briefy makes the case for IP v6 and includes a compact comparison of IP v6 and IP v4. Again, this is not a complete analysis of the pros and cons of the two addressing schemes, and the authors are upfront about this not being a top heavy comparison or analysis book. The second chapter introduces some ideas for network design including the Cisco preferred three layer (core, distribution, and access) architecture; a modular network architecture (edge, core, data-center, and services) and a presentation of the key design requirements or guidelines (modularity, hierarchy and resiliency). Chapter three presents design guidelines for one of the key issue in IP v6 adoption today; co-existence with IP v4. IP v4 networks and hosts still far outrank IP v6, and this is expected to continue for many years to come - even with the rapid growth in the number of IP v6 native devices and systems and an expected explosion in the number of IP v6 only devices as well as the increasing mainstreaming of networked PAN devices and applications including wearable health care sensors, smart homes, networked automobiles etc. While not the final say in co-existence, the chapter provides a good framework for network managers and designers to work from. Chapter four is a lite tour of some IP v6 network services - multicast, QoS and routing. Chapters five through ten combine to form the deployment section covering six different deployment scenarios -scenarios that are evident in many enterprises. Chapter five is a broad overview of deployment issues include suggestions on risk topics to consider, security issues, planning and piloting. Chapter six addresses campus deployment; seven addresses deployment in a virtualized environment; chapter eight is a guidelines for deployment in WAN and branch office networks; chapter nine addresses deployment in data centers and chapter 10 is on VPN and remote access deployment. Each chapter includes description of scenario-specific topology and protocol options and as a unit provide a useful guideline to network managers. The book is a cisco press book of course, and this is highlighted by the generous inclusion of IOS commands and screen dumps. Chapter 11, on management is another light walk-through of mostly IOS show and a few config commands. Again, this book is not your typical command or implementation reference manual - it is a design and architectural guide.
This book follows the custom of some others by Cisco Press where the authors are listed on the cover, along with their CCIE numbers. What this signifies is that they are defined by Cisco as qualified engineers on Cisco equipment. Unsurprisingly then, the book relates to a Cisco-only universe of hardware. So when you see the blurb on the cover about 'practical guide to deploying IPv6...', keep this in mind. So yes, at some level, this book is a glorified advertising brochure. But it does in several places rise about this. Sometimes by sheer level of detail. So even if it ignores hardware by other vendors, it does qualify as an authoritative manufacturer's hardware manual. At other times, the discussion is general enough to apply across the industry. Like when it talks about the exhaustion of the IPv4 address space and the subsequent need to migrate to IPv6. The first 5 chapters have this broad aspect. But from chapter 6 onwards, the narrative gets closer to implementation level. And specific Cisco models appear. So if your network is indeed mostly or all-Cisco then this is very germane. Then I got to chapters 9 and 10. A pleasant surprise was that other vendors' equipment and software make their appearance. Kudos to the authors for this outreach! There was prominent mention of Microsoft and VMware's IPv6-related offerings.
