This chapter covers the following topics:
Understanding Route Maps—Describes what route maps are and how to formulate them.
Configuring Route Maps—Describes how to configure route maps.
Monitoring the Configuration of Route Maps and Redistribution—Describes the commands used to monitor and troubleshoot route maps.
The topics in this chapter deal with controlling routing traffic with route maps, which are similar to, but more sophisticated than, access lists. This is an advanced topic that deals with programming the router to match criteria against assigned lists and to perform tasks based on the result of the match.
The chapter deals with why route maps are needed and how they work. This chapter also provides the configuration syntax with working examples.
The purpose of the "Do I Know This Already?" quiz is to help you decide what parts of this chapter to use. If you already intend to read the entire chapter, you do not necessarily need to answer these questions now.
The 10-question quiz, derived from the major sections in the "Foundation Topics" portion of the chapter, helps you determine how to spend your limited study time.
Table 12-1 outlines the major topics discussed in this chapter and the "Do I Know This Already?" quiz questions that correspond to those topics.

|Understanding Route Maps||1–5|
|Configuring Route Maps||6–8|
|Monitoring the Configuration of Route Maps and Redistribution||9–10|
The goal of self-assessment is to gauge your mastery of the topics in this chapter. If you do not know the answer to a question or are only partially sure of the answer, you should mark this question wrong for purposes of the self-assessment. Giving yourself credit for an answer you correctly guess skews your self-assessment results and might provide you with a false sense of security.
