A note to students and teachers

This manual was developed to prepare students for hands-on training to

accompany classroom lectures on CISCO networking theory for the CISCO CCNA

examination. These labs are intended to supplement and enhance the Cisco Networking

Academy Program with additional information, explanations, and laboratory materials,

not to replace them. Think of this like a “cliff’s notes” to accompany the curriculum. If

you are looking for a lot of theory, then you have got the wrong book.

This book uses a bunch of educational theory and the book should be used from

the start to the finish. For example, in early labs ip addresses and related information is

given. The later labs assume you have a good grasp of addressing and can choose your

own. Yeah, I know it can stink but understanding subnetting is a critical part of an entry-

level technician in networking and the “standard” Cisco curriculum does not address this

very well. Also I put an emphasis on troubleshooting and critical thinking to a much

deeper extent than the official curriculum. All labs and exercises contain four basic parts:

1. An objective section giving a brief topic for exploration in the lab or exercise

2. A tools and materials list

3. Steps needed to complete the lab or exercise

4. Supplemental lab or exercise challenge activities

Some sections include background information if needed.

Please keep in mind that equipment and IOS variations can cause differences

between what is within this book and what you may actually see.

Some of the labs contain “guest router names” that are borrowed from computer

security history. I do this to spice up the labs a bit and give you a cross-reference and

some history of computer security. I even got an email from a past member of the LOD

which was really cool. Keep them emails coming!

Keep track of updates and changes at http://www.spcollege.edu/star/cisco Scroll to

the bottom of the page and click on the “Lab Manual Edits.”

Do you have a lab that you want in this book? Send it in and we’ll give you written

credit for developing the lab if we pick it for use in our next book. We do, however,

reserve the right to reformat the “look” of the lab to be similar to the style in this book

and to do any minor edits. Before it appears in the newest version of the book you will

still have the final say-so on any changes. After all this is about an open source effort

and I feel giving the book away embodies the spirit of open source. The labs must be

done using MS Word or compatible format. Sorry to all the Mac/OS users.

anyway?

I want to give a special thanks to all of my students, colleagues, friends, etc. who have

pointed out the errors in this book (and sometimes the ones not in the book)…In the

future this list will also include anyone else who finds an error and brings it to my

attention: Rick Whelan, John Madison, Rich Curtis, Jessie Brown, Chad Olsen, Erik

Kruk, Thomas Banea,

LAN Routing Fundamentals

They said “I was crazy!”

How do you like the idea of free and low-cost textbooks? Well here is how

you can help me in the effort to bring more of these types of books to you.

They say there is safety in numbers, well I can promote this type of textbook

production way better if I hear from you personally. Send me an email at

[email protected] just to tell me you are using the book, you like the

idea of cheaper high-quality books, or to just say “hello.” Together we will

change education for the better!

Basic Router Commands

Objective:

To become familiar with basic router commands including how to get help.

Background:

In this lab we take you into the mysterious world of the router. You kind of messed

around with it before with the Hyperterminal lab, but eventually you new you would be

learning by doing. In this lab you will become familiar with the help commands, the

types of prompts you will use, and some basic router commands.

Lab Design:

Step-by-Step Instructions:

1. In the lab design above fill in the types of cables used (xo, ro, st) and into which

port they will be inserted.

2. Cable the lab as shown.

3. Open the hyperterminal session on the workstation.

4. Turn the power on to the router and watch the text as the router boots. In a couple

of labs you will learn the sequencing and purpose for all of that information.

Finally the router will prompt you with the message:

--- System Configuration Dialog ---

Would you like to enter the initial configuration dialog?

[yes/no]: n

5. If you put in “yes” then you will be able to set up your router using “menu-based”

commands. But you didn’t come here to learn how to do anything menu-based.

The menu-based commands are severely limited so you need to learn about

command line interfaced (CLI) configuration anyways so you might as well dive

right in! Put in either “no” or “n” (without the quote marks) and press enter. Also

put in “yes” for terminating autoinstall. You should see something similar to:

Would you like to terminate autoinstall? [yes/no] y

Press RETURN to get started!
