Cisco products make it simple for people to access and transfer information without regard to differences in time, place, or platform. Cisco answers this need with a wide range of hardware products that form information networks using the Cisco Internetwork Operating System IOS software. This software provides network services, paving the way for networked technical support and professional services to maintain and opti- mize all network operations.

Along with the Cisco IOS, one of the services Cisco created to help sup- port the vast amount of hardware it has engineered is the Cisco Certified Internetwork Expert CCIE program, which was designed specifically to equip people to effectively manage the vast quantity of installed Cisco net- works.

The business plan is simple: If you want to sell more Cisco equipment and have more Cisco networks installed, ensure that the networks you install run properly. Introduction xxv installing, managing, and troubleshooting them. This program, known colloquially as the Doctorate of Network- ing, has also been very successful, primarily due to its extreme difficulty.


Building upon the highly successful CCIE program, Cisco Career Certifi- cations permit you to become certified at various levels of technical profi- ciency, spanning the disciplines of network design and support.

Before these new certifications, you took only one test and were then faced with the lab, which made it difficult to succeed. With these new certifications, which add a better approach to preparing for that almighty lab, Cisco has opened doors that few were allowed through before. So, what are these new certifications and how do they help you get your CCIE? With the new certification programs, Cisco has created a type of stepping-stone approach to CCIE cer- tification.

Cisco, not unlike Microsoft or Novell, has created the certification process to give administrators a set of skills and to equip prospective employers with a way to measure skills or match certain criteria. Becoming a CCNA can be the initial step of a successful journey toward a new, highly rewarding, and sustainable career. To meet the CCNA certification skill level, you must be able to understand or do the following: Provide remote access by integrating dial-up connectivity with tradi- tional, remote LAN-to-LAN access, as well as supporting the higher levels of performance required for new applications such as Internet commerce, multimedia, etc.

The first step to becoming a CCNA is to pass one little test and—poof! Introduction xxvii but you still have to possess enough knowledge to understand and read between the lines—trust me what the test writers are saying. Each student gets hands-on experience by configuring at least two routers and a switch. See www. In addition, Cyberstate University provides hands-on Cisco router courses over the Internet using the Sybex Cisco Certification series books. Go to www. And Keystone Learn- ing Systems www.

This book will give you the background necessary before jumping into more advanced net- working with Cisco routers.

The CCNP program will prepare you to understand and comprehensively tackle the internetworking issues of today and beyond—and it is not limited to the Cisco world.

You will undergo an immense metamorphosis, vastly increasing your knowledge and skills through the process of obtaining these certifications. Cisco demands a certain level of proficiency for its CCNP certification. Improve network security. Create a global intranet. Provide access security to campus switches and routers. Provide increased switching and routing bandwidth—end-to-end resiliency services.

Provide custom queuing and routed priority services. Exam Switching This exam tests your knowledge of the and series of Catalyst switches. The CCNP: Switching Study Guide Sybex, summer covers all the objectives you need to understand to pass the Switching exam. Remote Access This exam tests your knowledge of installing, configuring, monitoring, and troubleshooting Cisco ISDN and dial-up access products. Remote Access Study Guide Sybex, summer covers all the exam objectives. Good luck!

Remember that test objectives and tests can change at any time without notice. Always check the Cisco Web site for the most up-to-date information www.

Cisco has added new sites lately for the CCIE lab; it is best to check the Cisco Web site for the most current information.

The CCIE Routing and Switching exam includes the advanced technical skills that are required to maintain optimum network performance and reliability, as well as advanced skills in supporting diverse networks that use disparate technologies. For example, a CCIE has the following skills down pat: To pass this test, you must understand how to do the following: Use Network-layer addressing.

Filter with access lists. Use and propagate VLAN. Size networks. CCDP certification skills include the following: Introduction xxxiii 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: This book covers everything you need to know in order to become CCNA certified.

However, taking the time to study and practice with routers or a router simulator is the real key to success. The information you will learn in this book, and need to know for the CCNA exam, is listed in the following bullet points: Chapter 1 introduces you to internetworking.

You will learn the basics of the Open Systems Interconnection the way Cisco wants you to learn it. Also, the Cisco three-layer hierarchical model will be dis- cussed, along with how to choose Cisco equipment based on this model. Ethernet networking and standards are discussed in detail in this chapter as well.

Chapter 2 gives you a background on layer-2 switching and how switches perform address learning and make forwarding and filtering decisions. This in-depth chapter covers the very beginnings of the Internet Protocol stack and then goes all the way to IP addressing and subnetting.

If you read this chapter carefully, you will be able to subnet a network in your head!

IP configuration will be discussed and a hands-on lab will help you gain a firm grasp of the concepts taught in the chapter. Chapter 5 teaches you about IP routing. This is a fun chapter, because you will begin to build your network, add IP addresses, and route data between routers.

You will also learn about static, default, and dynamic routing in this chapter. Written and hands-on labs will help you understand IP routing to the fullest.

Chapter 6 covers Virtual LANs and how you can use them in your internetwork. Written labs and review questions will reinforce the VLAN material. Chapter 7 provides you with the management skills needed to run a Cisco ISO network. Backing up and restoring the IOS, as well as router configuration, is covered, as are troubleshooting tools neces- sary to keep a network up and running. Chapter 8 introduces you to the wonderful world of Novell IPX. Chapter 9 covers access lists, which are created on routers to filter the network.

Written and hands-on labs, along with review questions, will help you study for the access-list portion of the CCNA exam. Chapter 10 concentrates on Cisco Wide Area Network protocols. You must be proficient in all these protocols to be successful on the CCNA exam.

Appendix A is a practice exam. If you think you are ready for the CCNA exam, see if you can get by my practice exam. A second prac- tice exam is located on the CD as well. Appendix B discusses configuring a Catalyst switch. Introduction xxxv answering the review questions should prepare you well for the CCNA exam. It is a great reference if you need to look up what a certain command does and is used for. The Glossary is a handy resource for Cisco terms. This is a great tool for understanding some of the more obscure terms used in this book.

Then I go back through and dig in to the fuzzy parts. After I feel that I have a working knowledge of the topics I need to know, I like to use the Exam Cram series to make sure I've hit the high spots before I test.
