Introduction

Introduction

The Cisco Certified Network Professional (CCNP®) Routing and Switching certification validates knowledge and skills required to install, configure and troubleshoot converged local and wide area networks with 100 to 500 or more nodes. With a CCNP Routing and Switching certification, a network professional demonstrates the knowledge and skills required to manage the routers and switches that form the network core, as well as edge applications that integrate voice, wireless, and security into the network.

The CCNP Quick Reference was written to help you prepare for the three exams in the CCNP Routing and Switching certification. Some readers tell us that they use this book before beginning their exam preparation, to find which areas they are weak in. This helps target their studying. Others use it after studying or taking the course as a concise learning resource during their final preparation for the exam.

This book will also help once your exams are over, when you need a quick answer about a technology, or a reminder about configuration steps.

Who Should Read This Book?

Current and aspiring network engineers will find this book useful in two ways. First, those preparing for the CCNP Routing and Switching certification will appreciate the targeted review of exam topics. It will help them understand the technologies, not just memorize questions. This will lead to success on the exam and improved on-the-job performance. Secondly, the book serves as a reference for those not pursuing the certification. Its short descriptions and many examples come in handy when you need a fast answer to a question, or to configure something quickly. It deserves a place on every network engineer’s bookshelf.

How This Book Is Organized

The book is organized by exam, and in the order that most people take the exams. ROUTE is first, followed by SWITCH, and then TSHOOT. The topics within each exam section coorespond with those on the exam blueprint. This edition as a whole include more emphasis on planning and verifying network changes than the previous edition. There is more information on troubleshooting commands throughout the entire book, in addition to the TSHOOT section. Following is a description for each section.

Chapter 4: Optimizing Routing

This chapter examines various methods of controlling routing updates, such as route maps, prefix lists, and distribute lists. It describes how to configure route maps, and how to use them for policy-based routing, controlling route redistribution, and tagging routes. Route redistribution planning and isses are described, redistribution configuration is demonstrated.

Chapter 5: Path Control

Chapter 5 covers some additional ways to control the path that traffic takes. These include offset-lists, IP SLA, policy-based routing, Optimized Edge Routing, and VRFs. IP SLA tracking is shown along with route maps to provide backup routes when using policy-based routing.

Chapter 6: BGP and Internet Connectivity

Whether or not to use BGP is the first topic discussed in Chapter 6. Different types of ISP connections are covered. The chapter gives an overview of BGP operation and basic configuration. BGP path selection is covered, along with ways to influence the path selection and ways to filter routes. Additionally, ways to verify BGP operation are shown.

Chapter 7: Branch Office Connectivity

Chapter 7 considers branch office routing design and implementation. This includes a description of DSL with PPPoA, and IPsec VPNs. Dynamic routing over various types of tunnels is covered, and a GRE tunnel configuration is shown. The chapter ends with a look at EIGRP load sharing.

Chapter 8: Mobile Worker Connectivity

Chapter 8 covers the network changes necessary to allow mobile workers to connect to the corporate network. The services needed to enabled this are discussed, including NAT, DHCP, firewalling, VPNs, and routing.

Chapter 9: IPv6 Introduction

This rather in-depth introduction to IPv6 covers the IPv6 address format, ways for hosts to acquire their addresses, and IPv6 routing for RIP, EIGRP, OSPF, and BGP. It also includes strategies for integrating IPv4 and IPv6 such as various types of tunnels. IPv6 operation over various types of links is additionally covered.

SWITCH
