Cisco—A Brief History

Many readers may already be familiar with Cisco and what they do ever, those of you who are new to the field, just coming in fresh from your MCSE, and those of you who maybe have 10 or more years in the field but wish to brush up on the new technology may appreciate a little background

How-on Cisco

Introduction xxvii

In the early 1980s, Len and Sandy Bosack, a married couple who worked

in different computer departments at Stanford University, were having trouble getting their individual systems to communicate (like many married people)

So in their living room they created a gateway server that made it easier for their disparate computers in two different departments to communicate using

a small commercial gateway server product that changed networking ever Some people think the name was intended to be San Francisco Systems but the paper got ripped on the way to the incorporation lawyers—who knows? In 1992, the company name was changed to Cisco Systems, Inc.The first product the company marketed was called the Advanced Gate-way Server (AGS) Then came the Mid-Range Gateway Server (MGS), the Compact Gateway Server (CGS), the Integrated Gateway Server (IGS), and the AGS+ Cisco calls these “the old alphabet soup products.”

for-In 1993, Cisco came out with the amazing 4000 router and then created the even more amazing 7000, 2000, and 3000 series routers These are still around and evolving (almost daily, it seems)

Cisco has since become an unrivaled worldwide leader in networking for the Internet Its networking solutions can easily connect users who work from diverse devices on disparate networks Cisco products make it simple for people to access and transfer information without regard to differences

in time, place, or platform

In the big picture, Cisco provides end-to-end networking solutions that customers can use to build an efficient, unified information infrastructure of their own or to connect to someone else’s This is an important piece in the Internet/networking–industry puzzle because a common architecture that delivers consistent network services to all users is now a functional impera-tive Because Cisco Systems offers such a broad range of networking and Internet services and capabilities, users who need to regularly access their local network or the Internet can do so unhindered, making Cisco’s wares indispensable

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 port the vast amount of hardware it has engineered is the Cisco Certified Internetwork Expert (CCIE) program, which was designed specifically to

sup-xxviii Introduction

equip people to effectively manage the vast quantity of installed Cisco 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

net-Clearly, having a fabulous product line isn’t all it takes to guarantee the huge success that Cisco enjoys—lots of companies with great products are now defunct If you have complicated products designed to solve compli-cated problems, you need knowledgeable people who are fully capable of installing, managing, and troubleshooting them That part isn’t easy, so Cisco began the CCIE program to equip people to support these complicated networks This program, known colloquially as the Doctorate of Network-ing, has also been very successful, primarily due to its extreme difficulty

Cisco continuously monitors the program, changing it as it sees fit, to make sure that it remains pertinent and accurately reflects the demands of today’s internetworking business environments

Building upon the highly successful CCIE program, Cisco Career cations permit you to become certified at various levels of technical profi-ciency, spanning the disciplines of network design and support So, whether you’re beginning a career, changing careers, securing your present position,

Certifi-or seeking to refine and promote your position, this is the book fCertifi-or you!

Cisco’s Network Support Certifications

Initially, to secure the coveted CCIE, you took only one test and then you were faced with the (extremely difficult) lab, an all-or-nothing approach that made

it tough to succeed In response, Cisco created a series of new certifications

to help you get the coveted CCIE, as well as aid prospective employers in measuring skill levels With these new certifications, which added a better approach to preparing for that almighty lab, Cisco opened doors that few were allowed through before So, what are these stepping-stone certifications and how do they help you get your CCIE?

Cisco Certified Network Associate (CCNA)

The CCNA certification was the first in the new line of Cisco certifications, and was the precursor to all current Cisco certifications With the new certification programs, Cisco has created a type of stepping-stone approach

to CCIE certification Now, you can become a Cisco Certified Network

Introduction xxix

don’t have to stop there—you can choose to continue with your studies and achieve a higher certification, called the Cisco Certified Network Profes-sional (CCNP) Someone with a CCNP has all the skills and knowledge he

or she needs to attempt the CCIE lab However, because no textbook can take the place of practical experience, we’ll discuss what else you need to be ready for the CCIE lab shortly

Why Become a CCNA?

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

The CCNA program was created to provide a solid introduction not only

to the Cisco Internetwork Operating System (IOS) and Cisco hardware, but also to internetworking in general, making it helpful to you in areas that are not exclusively Cisco’s At this point in the certification process, it’s not unrealistic to imagine that future network managers—even those without Cisco equipment—could easily require Cisco certifications for their job applicants

If you make it through the CCNA and are still interested in Cisco and internetworking, you’re headed down a path to certain success

What Skills Do You Need to Become a CCNA?

To meet the CCNA certification skill level, you must be able to understand

or do the following:

switched LAN and LANE networks

Frame Relay, IP RIP, VLANs, IPX RIP, Ethernet, and access lists

bandwidth and WAN costs, using features such as filtering with access lists, bandwidth on demand (BOD), and dial-on-demand routing (DDR)

xxx Introduction

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

How Do You Become a CCNA?

The first step to becoming a CCNA is to pass one little test and—poof!—

you’re a CCNA (Don’t you wish it were that easy?) True, it’s just one test, but you still have to possess enough knowledge to understand (and read between the lines—trust me) what the test writers are saying

I can’t stress this enough—it’s critical that you have some hands-on rience with Cisco routers If you can get a hold of some 2500 routers, you’re set But if you can’t, we’ve worked hard to provide hundreds of configura-tion examples throughout this book to help network administrators (or people who want to become network administrators) learn what they need

expe-to know expe-to pass the CCNA exam

One way to get the hands-on router experience you’ll need in the real world

is to attend one of the seminars offered by GlobalNet Training Solutions, Inc., which is owned and run by myself The seminars are 5 days and 11 days long and will teach you everything you need to become a CCNA (or even a CCNP)

Each student gets hands-on experience by configuring at least two routers and

Cisco Certified Network Professional (CCNP)

So you’re thinking, “Great, what do I do after passing the CCNA exam?”

Well, if you want to become a CCIE in Routing and Switching (the most popular certification), understand that there’s more than one path to that much-coveted CCIE certification The first way is to continue studying and become a Cisco Certified Network Professional (CCNP), which means four more tests, in addition to the CCNA certification

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

Introduction xxxi

While you don’t need to be a CCNP or even a CCNA to take the CCIE lab, it’s extremely helpful if you already have these certifications

What Skills Do You Need to Become a CCNP?

Cisco demands a certain level of proficiency for its CCNP certification In addition to mastering the skills required for the CCNA, you should be able

to do the following:

routed WAN, and switched LAN networks, along with dial-access services

AppleTalk, extended access lists, IP RIP, route redistribution, IPX RIP, route summarization, OSPF, VLSM, BGP, serial, IGRP, Frame Relay, ISDN, ISL, X.25, DDR, PSTN, PPP, VLANs, Ethernet, ATM LAN emulation, access lists, 802.10, FDDI, and transparent and translational bridging

net-work response times, and improve reliability and quality of service

remote access

resiliency services

How Do You Become a CCNP?

After becoming a CCNA, the four exams you must take to get your CCNP are as follows:

funda-mentals learned in the CCNA course It focuses on large multiprotocol internetworks and how to manage them with access lists, queuing, tun-neling, route distribution, route maps, BGP, EIGRP, OSPF, and route

objectives you need to understand to pass the Routing exam

xxxii Introduction

(Sybex) covers all the objectives you need to understand to pass the Switching exam

skills needed for Ethernet and Token Ring LANs, IP, IPX, and AppleTalk

Support Study Guide (Sybex) covers all the objectives you need to stand to pass the Support exam

installing, configuring, monitoring, and troubleshooting Cisco ISDN and dial-up access products You must understand PPP, ISDN, Frame Relay,

covers all the exam objectives

www.routersim.com has a complete Cisco router simulator for all CCNP exams.

If you hate tests, you can take fewer of them by signing up for the CCNA exam and the Support exam and then taking just one more long exam called the Foundation R/S exam (640-509) Doing this also gives you your CCNP—

but beware; it’s a really long test that fuses all the material Routing, ing, and Remote Access exams into one exam Good luck! However, by taking this exam, you get three tests for the price of two, which saves you

Switch-$100 (if you pass) Some people think it’s easier to take the FoundationR/S exam because you can leverage the areas that you would score higher in against the areas in which you wouldn’t

Remember that test objectives and tests can change at any time without notice Always check the Cisco website for the most up-to-date information ( www.cisco.com ).

Cisco Certified Internetwork Expert (CCIE)

You’ve become a CCNP, and now you fix your sights on getting your Cisco Certified Internetwork Expert (CCIE) in Routing and Switching—what do

Introduction xxxiii

you do next? Cisco recommends that before you take the lab, you take the Cisco Internetwork Design (CID) exam (640-025) and the Cisco-authorized course called Installing and Maintaining Cisco Routers (IMCR) By the way,

no Prometric test for IMCR exists at the time of this writing, and Cisco

the CCIE lab After jumping those hurdles, you then have to pass the R/S Exam Qualification (350-001) before taking the actual lab

CCIE-How Do You Become a CCIE?

To become a CCIE, Cisco recommends you do the following:

center and pony up around $15,000–$20,000, depending on your corporate discount

pass it the first time)

many people fail two or more times (Some never make it through!) Also, there are a limited number of places to take the lab: San Jose, California; Research Triangle Park, North Carolina; Sydney,

Australia; Halifax, Nova Scotia; Tokyo, Japan; and Brussels, Belgium This means that you might just need to add travel costs to that $1,000 Cisco has added new sites lately for the CCIE lab; it is best to check the Cisco website for the most current information

Cisco has changed the CCIE lab from a two-day to a one-day lab Please see www.cisco.com for the latest information.

What Skills Do You Need to Become a CCIE?

The CCIE Routing and Switching exam includes the advanced technical skills that are required to maintain optimum network performance and reli-ability, as well as advanced skills in supporting diverse networks that use disparate technologies CCIEs just don’t have problems getting jobs; these experts are basically inundated with offers to work for six-figure salaries But that’s because it isn’t easy to attain the level of capability that is mandatory

xxxiv Introduction

for Cisco’s CCIE For example, a CCIE can easily do the following:

routed WAN, switched LAN, and ATM LANE networks, and access services

encapsulation and layering; windowing and flow control, and their relation to delay; error detection and recovery; link-state, distance vector, and switching algorithms; management, monitoring, and fault isolation

services provided by Desktop, WAN, and Internet groups—as well as the functions; addressing structures; and routing, switching, and bridging implications of each of their protocols

platforms, architectures, and applications; communication servers;

protocol translation and applications; configuration commands and system/network impact; and LAN/WAN interfaces, capabilities, and applications

networks

Sybex’s CCIE: Cisco Certified Internetwork Expert Study Guide (2001) will help you prepare for and pass the CCIE exam.

Cisco’s Network Design Certifications

In addition to the network support certifications, Cisco has created another certification track for network designers The two certifications within this track are the Cisco Certified Design Associate and Cisco Certified Design

Professional certifications If you’re reaching for the CCIE stars, we highly recommend the CCNP and CCDP certifications before attempting the lab (or attempting to advance your career).

This certification will give you the knowledge you need to design routed LAN, routed WAN, and switched LAN and ATM LANE networks

Cisco Certified Design Associate (CCDA)

To become a CCDA, you must pass the Designing Cisco Networks (DCN) exam (640-441) To pass this test, you must understand how to do the following:

ATM LANE networks

The Sybex CCDA: Cisco Certified Design Associate Study Guide (1999) is the

most cost-effective way to study for and pass your CCDA exam.

Cisco Certified Design Professional (CCDP)

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:

and ATM LANE networks

CCDPs must also demonstrate proficiency in the following:

VLAN use and propagation

switch-ing engines; memory, cost, and minimization

What Does This Book Cover?

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:

basics of the Open Systems Interconnection model the way Cisco wants you to learn it Ethernet networking and standards are dis-cussed in detail in this chapter as well There are written labs and plenty of review questions to help you Do not skip the labs in this chapter!

switches perform address learning and make forwarding and filtering decisions Network loops and how to avoid them with the Spanning Tree Protocol (STP) will be discussed, as well as the different LAN switch types used by Cisco switches Go through the written lab and review questions

the exam as well as in the real world by discussing TCP/IP 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!

Plenty of help is found in this chapter if you do not skip the written lab and review questions

Tips for Taking Your CCNA Exam

The CCNA test contains about 50 questions to be completed in about

90 minutes This can change per exam You must get a score of about 82%

to 85% to pass this exam, but again, each exam can be different

Many questions on the exam have answer choices that at first glance look identical—especially the syntax questions! Remember to read through the

choices carefully, because close doesn’t cut it If you get commands in the wrong order or forget one measly character, you’ll get the question wrong

So, to practice, do the hands-on exercises at the end of the chapters over and over again until they feel natural to you

Also, never forget that the right answer is the Cisco answer In many cases,

more than one appropriate answer is presented, but the correct answer is the

one that Cisco recommends

The CCNA 640-607 exam includes the following test formats:

at www.routersim.com that accepts partial responses just as an actual Cisco router will

The software on the CD and at RouterSim.com provides step-by-step instruction on how to configure both Cisco routers and switches However, router simulations in Cisco proctored exams will not show the steps to fol-low in completing a router interface configuration They do allow partial command responses For example, show config or sho config or sh conf would be acceptable Router #show ip protocol or router # show ip prot would be acceptable The exam commands must include the correct spacing, spelling, and punctuation marks (such as #@!?)

Here are some general tips for exam success:

you’re clear about exactly what each question asks.

When answering multiple-choice questions that you’re not sure about, use the process of elimination to get rid of the obviously incorrect answers first Doing this greatly improves your odds if you need to make an educated guess.

After you complete an exam, you’ll get immediate, online notification

of your pass or fail status, a printed Examination Score Report that indicates your pass or fail status, and your exam results by section (The test admin-istrator will give you the printed score report.) Test scores are automatically forwarded to Cisco within five working days after you take the test, so you don’t need to send your score to them If you pass the exam, you’ll receive confirmation from Cisco, typically within two to four weeks
