Description:  

An
essential, comprehensive, and practical guide to IPv6 concepts, service
implementation, and interoperability in existing IPv4 environments
 
After
completing Deploying IPv6 Networks, you will:

Understand the current state of IPv6
technologies and services
Understand the IPv6 features as they are
applied in service deployments
Be prepared with guidelines on how to ready
your organization for a migration to IPv6
Know how to design and implement an IPv6
production-level network using the book’s templates and examples
Have the ability to configure and troubleshoot
IPv6 networks
Know where IPv6 developments are moving in the
future
Large IPv6
production deployments worldwide are proof that the transition to the next
generation of the IP protocol is no longer merely a prediction—IPv6 is now
touching all aspects of IP networking and communications. Therefore,
understanding the technology and being able to plan, design, and deploy IPv6
services are necessary skills for networking professionals.
 
Deploying IPv6 Networks is an essential guide to IPv6 concepts,
service implementation, and interoperability in existing IPv4 environments.
You’ll learn about IPv6 as a mature technology ready for deployment.
Deploying IPv6 Networks goes beyond addressing the basics of IPv6 yet
remains accessible to readers unfamiliar with the protocol. With this book in
hand, you will learn how to plan, design, deploy, and manage IPv6
services.
 
Deploying IPv6 Networks opens with an updated “Case for IPv6”: a
review of the IPv4 challenges and the IPv6 opportunities. It then covers the
IPv6 concepts related to IP services provided in real networks. Relevant
features and corresponding configuration examples are presented in a
deployment context as they are applied to the various segments of the network.
The IPv6 knowledge accumulated in the first part of the book is revisited in
Part II, where it is leveraged in concrete and usable examples that cover most
common network environments: MPLS service provider, IP service provider, and
enterprise.
The
structure of Deploying IPv6 Networks enables you to use it as a
reference for specific aspects of IPv6, as a technology study guide, or as a
design guide for deploying IPv6. You’ll also find that the presentation
approach enables you to leverage your IPv4 experience to
quickly become knowledgeable and proficient with the concepts of
IPv6.
