Introduction

Cisco Certified Design Professional (CCDP) 2.0

If you're already a CCNP and want to get your CCDP, you can simply take
the CID 640-025 test. If you're not yet a CCNP, however, you must take the
CCDA, CCNA, Routing, Switching, Remote Access and CID exams.

CCDP certification skills include the following:

Designing complex routed LAN, routed WAN, and switched LAN
and ATM LANE networks

Building upon the base level of the CCDA technical knowledge

CCDPs must also demonstrate proficiency in the following:

Network-layer addressing in a hierarchical environment

Traffic management with access-lists

Hierarchical network design

VLAN use and propagation

Performance considerations: required hardware and software; switch-
ing engines; memory, cost, and minimization

What Does This Book Cover?

This book covers everything you need to pass the CCNP Cisco Internetworking
Troubleshooting exam. It teaches you how to troubleshoot processes on Cisco
Routers and Catalyst Switches. Each chapter begins with a list of the topics cov-
ered related to the CCNP Support test, so make sure to read them over before
working through the chapter.

Chapter 1 starts with learning about the troubleshooting methodology

that should be followed to successfully resolve network problems. Different
troubleshooting approaches will be discussed.

These different troubleshooting approaches are the foundation of the

application of knowledge that will be gained throughout the book. Chapter
2 discusses Layer 2 and Layer 3 technologies and protocols. An overview is
provided for all major LAN and WAN protocols.

Chapter 3 gives you an introduction to generic troubleshooting tools.

This chapter is dedicated to making you familiar with all of the different
troubleshooting tools that are available to effectively troubleshoot net-
work problems. You move on from there to Chapter 4, in which you
learn about Cisco's diagnostic commands. The infrastructure of high-
and low-end routers is discussed in detail, as well as the switching paths
used by each. Some global Cisco commands are also covered. Chapter
5 teaches you how to apply the commands and tools that are learned in
previous chapters.
