This chapter covers the following topics:
Configuring EIGRP—This section describes the basic configuration commands necessary to support routing.
Verifying the EIGRP operation—This section describes show and debug commands that will help evaluate the status of EIGRP.
Troubleshooting EIGRP—This section describes the process of diagnosing and repairing EIGRP problems.
This chapter details steps to configure EIGRP for IP routing. This chapter assumes general knowledge of routing protocols and the terminology, concepts, and operation of EIGRP (from Chapter 3, "EIGRP Principles"). This chapter introduces EIGRP configuration commands by explaining the required commands and then discussing the optional configuration commands that you can use.
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 12-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 4-1 outlines the major topics discussed in this chapter and the "Do I Know This Already?" quiz questions that correspond to those topics.

|Verifying the EIGRP Operation||8–10|
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 the question wrong for purposes of the self-assessment. Giving yourself credit for an answer you correctly guessed skews your results and might provide you with a false sense of security.
