Legal Notice The advice in this book is designed to assist you in reaching the required standard for the CCENT/ICND1 and CCNA exams. The labs are designed to illustrate various learning points and are not suggested configurations to apply to a production network. Please check all your configurations with a qualified Cisco professional. Many of the commands, including debugs and clearing the IP routing table, can cause serious performance issues on live networks. Introduction to the 2 Edition nd It’s hard to believe that I wrote the first edition of this book in 2009. Back then, the CCNA exam was mostly theory with a couple of labs thrown in. Scroll forward eight years and the exam is mostly hands-on labs and practical questions with some theory thrown in. A hands-on lab manual was needed because there was a huge gap in the market for a practical manual. Most CCNA books are very theory heavy with a few labs thrown in. My CCNA study manuals Cisco CCNA Simplified and Cisco CCNA in 60 Days addressed this problem by being very lab heavy. After feedback from my students, I felt that most people would need an extra boost of practical experience for the CCNA exam. In the CCNA exam, you can expect to be tested on the following hands-on scenarios: 1. Configure a lab according to specifications. 2. Troubleshoot and resolve a broken network or technology (e.g., ACL not working). 3. Use show commands to determine an issue or configuration and answer questions. It gets even harder when you realize that you are not familiar with the topology and IP addressing scheme, and you will see the clock counting down before your eyes. You will be working on a router or switch emulator that only runs a limited number of IOS commands so some of your shortcuts may not work, such as sh ip int brie instead of show ip interface brief. The goal of this lab manual is to get your hands-on skills way past the level required for the CCNA exam so when it comes to exam day, you will find the lab scenarios a breeze. I’ve had many of my students finish their exam with 30 minutes to spare because they solved the scenarios so quickly! This is where you should aim to be. The fact that you have this book in your hands means that you are studying for your CCNA or CCENT exam or perhaps just want to polish your hands-on Cisco skills. Whatever your reason, we admire you for putting the effort into improving your hands- on ability. We have marked the labs as either ICND1, ICND2, CCNA, or CCENT, but please do double-check the syllabus before you take the exam. We have also rated each lab on a scale of 1 to 10 for difficulty and have given you timings so you will know when you are ready for the real thing. Best of luck with your studies.

How to Use This Book First, this book is designed to cement the theory you have read in your CCNA study guide. If you don’t have a good-quality study guide at the moment, then we highly recommend one of our CCNA study guides—CCNA Simplified or Cisco CCNA in 60 Days—which you can purchase on Amazon in printed or Kindle format. CCNA Simplified is targeted at those who want to approach the exams at a leisurely pace, while CCNA in 60 Days is available to those who want to pass the exams quickly and need a well-defined structure to follow as opposed to working on their own study plan. The goal is to dramatically improve your hands-on knowledge and speed. We don’t have the space here to cover the theory at all, so please refer to your CCNA study guide to get a good understanding of the learning points behind each lab. Every lab is designed to cover a particular theory issue, such as configuration requirements of RIP passive interfaces. As the labs progress, common commands such as how to create VLANs or add IP addresses to interfaces will not be repeated. This not only saves space but after a couple of labs, you should really know how to do these commands. I am telling you this because I had a few complaints from readers about not spelling out how to add an IP address to an interface, but by the time you are configuring advanced access lists, you really should know how to do that without being prompted! If you want to take the two-exam route, Section One of the book covers the ICND1 topics, while Section Two presents the ICND2 topics. Each lab is followed by a solution so you can check yours against ours. Please bear in mind that Cisco has some subjects listed in both the ICND1 and ICND2 sections, such as native VLANs. Cisco also reserves the right to ask questions on the exam that are not even in the syllabus. I’m mentioning this because I sometimes get an e-mail from an angry student blaming me for the fact that something came up on the exam that I didn’t cover. Cisco also inserts test questions into the exam that are not marked, so don’t sweat too much if something out of the ordinary appears. I took a Cisco switching exam once and an EIGRP routing question appeared on the screen! Do your best to answer it and move on. As you progress through the labs, you will be given less and less configuration commands to follow, and instead you will simply refer to steps from previous labs. This is to cement the learning for you as well as to save space and time. The ICND1 and ICND2 sections finish with challenge labs but with a running configuration instead of a full solution. Look at the challenge and configure as much as you can without looking at the solution. After you finish, check your solution against ours. Sometimes there is more than one way to configure a particular technology, so don’t kick yourself if your solution works but is different than ours. Hands-on Options The best solution is to have your own home lab featuring Cisco routers and switches that you can cable up. Cisco tests you on the 15.X IOS release and the 2960 model of switch. There are various companies selling kits on eBay so check those out. You can resell them after your exam. GNS3 is a free router emulator. You can drag and drop routers and switches to easily create different topologies. You need to supply your own IOS and these are only legally available via Cisco, so this may prove a challenge to many students. Try it out for yourself though. Router simulators are available from a small number of companies. These do not run Cisco IOS but a programmer has created a number of commands that you can try out. I do not recommend that you use these because they aren’t able to create flexible topologies and they don’t act in the same way actual devices do. A few companies offer remote racks of live equipment. The number is fairly limited due to the costs of hosting the equipment, and of course somebody needs to physically attend to the site at times to recover it in some cases. Cisco offers a live lab solution, and there are two full racks available 24/7 to all members of https://www.howtonetwork.com. The last and best option for most students is Packet Tracer, which is now a free download from Cisco. It’s still an emulator but you can drag IP phones, routers, switches, and other devices to create fairly complex topologies. It acts in a very similar way to actual equipment but doesn’t offer all of the available commands. It’s good enough for the CCNA exam level but be aware that not all syllabus topics are supported, for example, extended VLANs. If you do not like router output interrupting you as you configure the labs, then please add the logging synchronous command to the console 0 line as shown below: Router#config t Router(config)#line console 0 Router(config-line)#logging synchronous A Note about Interfaces We have configured all of these labs on either our own Cisco equipment or the live racks at https://www.howtonetwork.com. Our interfaces match the diagrams for each lab, but please note that your equipment may have different interface numbers depending on the model. If you plugged your WIC card into a different slot, it may be numbered 0/0, 0/1, 1/0, 0/0/1, and so on. The best way to find your interface number is to issue the show ip interface brief command, and then mark it on the diagram. Even better, draw your own network diagram. We have done our best to prepare you for the real world of Cisco internetworking. To this end, we have abbreviated many of the commands. Nobody in the real world types config terminal to enter configuration mode on a router, but rather conf t usually. In the exam, you will be using a router simulator though, so please understand the full version of the command just in case the shortened version doesn’t work. Are You Exam Ready? The labs here are designed to prepare you well beyond the exam level and, of course, give you a strong foundation for real-world Cisco internetworking. But they are just the beginning. Before you take the actual exam, ensure that you can complete all the labs without looking at the solutions. Then change up the IP addressing scheme, change the interface types (if applicable), and add more routers or switches. Read up on the configuration and show commands using Cisco IOS documentation. You should be very familiar with all the ways that the technology can be broken, the relevant show command(s) to establish whether your theory is correct, and, of course, how to fix any issues and finally prove that the scenario is working with relevant debug or show commands, or even a packet sniffer. The sign of a student who I know will pass the exam is having a real interest in unpacking how the protocol works using theory, labs, and practice exams. Once you can do this you can easily plan, configure, verify, and troubleshoot anything in the syllabus. In fact, as soon as you look at a topology, you will know which commands should be present and which routes should be in the table (for example) on which router. Help—My Lab Isn’t Working A big part of being a network engineer is troubleshooting. Most of the mistakes you will make will result from mistyping stuff or misreading the instructions. It’s okay because this is part of the learning process. Double-check your configurations and then the solution. Please do bear in mind that different IOS versions support different commands. Packet Tracer doesn’t support everything in the CCNA syllabus (such as extended VLANS) so no matter how hard you try, the commands just won’t work. GNS3 isn’t live equipment so the clock rate command won’t work as it does on live equipment. The Telnet lines on most equipment go from 0 to 15, but on GNS3 it’s 0 to 903. If you try to configure a local password on the Telnet lines before adding a password on GNS3, you will get 1,001 error messages like the ones below: % Login disabled on line 999, until ‘password’ is set % Login disabled on line 1000, until ‘password’ is set % Login disabled on line 1001, until ‘password’ is set If things aren’t working for you the way you expect, then check your configurations. Check that the commands are supported on your platform (via the Cisco IOS feature set/platform tool) or just Google it. Try the lab out on PT and then GNS3, and if all else fails, get some time on live equipment if you can. Nothing beats it. For most of the labs we used live equipment, so some of your options and outputs may differ. Some commands may not be available to you and some of our show runs may differ slightly because Cisco enables/disables features depending on the IOS release and platform. If you see some slight differences, don’t let this trouble you too much, especially if you choose to use Packet Tracer, which offers a limited set of commands and debugs. Leave the lab and come back to it later with a fresh pair of eyes. Get a colleague to check it over or post the issue on a forum as a last resort. 101 CCNA Labs Video Course After writing this book, I had a large number of requests for a video course with me explaining the scenario and talking students through the solutions. I eventually did this and have put it on Udemy. The course matches most of this book with a few changes here and there. You certainly don’t need to use it but if you learn best by watching an instructor, then the link is below. I’ve added a coupon so that you can get access for $10, which covers the cost of the video production software and the weeks of work that went into creating it. https://www.udemy.com/101-cisco-ccna-labs/ Enter the coupon code below at checkout and the price will drop to $10: 101CCNA Or use the direct URL below: https://www.udemy.com/101-cisco-ccna-labs/?couponCode=101CCNA Once again, you don’t need the video course because I’ve designed this book as a stand- alone product, but if you want some extra teaching and have 10 bucks to spare, then check it out. Over 5,000 students have used it at the time of writing this new edition. Please drop me a review if you like it. You can also post questions and requests on that platform, and there is a certificate of completion.
