IPv6 Training Fundamentals

Duration: 2-3 days

Introduction

IPv6, or Internet Protocol Version 6, is the “next generation” protocol designed by the Internet Engineering Task Force (IETF) to gradually replace IPv4, the version that has been in use for nearly two decades. IPv6 overcomes some of the limitations of IPv4, such as the limited address space, while introducing a number of enhancements in areas such as routing and network autoconfiguration. IPv6 is expected to gradually replace IPv4, with the two coexisting for a number of years. With the momentum for migration to IPv6 growing worldwide, it has become an important area of study for all involved in internetworking.

This course deals with all of the key issues of implementing and configuring IPv6 networks. We will begin with a quick review of the IPv4 addressing, configuration, subnetting and routing functionality. We will then study the basics of IPv6 addressing and continue into the discussion of implementation and routing functions. We will finish up with a study of the mechanisms that facilitate the co-existence of IPv4 and IPv6.
