This chapter focuses on troubleshooting the IP routing process. To that end, it begins with a section about two important troubleshooting tools: ping and traceroute. Following that, the chapter examines the IP routing process from a troubleshooting perspective, particularly focusing on how to isolate routing problems to identify the root cause of the problem. The final section covers a wide variety of small topics, all of which can be useful when you're troubleshooting IP routing problems. The chapter also includes a helpful "do I know this already" quiz, to determine whether you need to read the full chapter or can move ahead to the exam preparation section.
