Then, compare the current network conditions to the normal situation and look for differences until you discover the root cause of those differences.This chapter begins with a review of the ICND1 book on how IPv6 works. Thankfully, IPv6 is very similar to IPv4 in many ways, with only a few significant differences in addressing. This section builds on these similarities, summarizing the core features of IPv6 and preparing you for a discussion of IPv6 troubleshooting.The second major section of this chapter covers each of the various problems that can occur in an IPv6 network. All of these issues are related to IPv6, and some of the problems that cause certain features to not function properly are also shown.16.1 "Do I Know This Already?" Mini-TestsThe chapters on troubleshooting in this book cover concepts from many other chapters and even include some chapters from the Cisco CCENT/CCNA ICND1 (100-101) Certification Exam Guide, along with answers to some of the more difficult questions on the CCNA exam, so readers should read these relevant chapters first, regardless of their current level of knowledge. For this reason, none of the troubleshooting chapters have a "Do I already know this?" quizzes. Of course, if you have a complete grasp of the IPv6 routing troubleshooting content in this book and the Cisco CCENT/CCNAICND1(100-101) Certification Exam Guide, you can skip most of this chapter and read the Exam Prep content directly.16.2 Fundamentals16.2.1 Common IPv6 Operations
