This book is intended to help you continue on your exciting new path toward obtaining your CCNP and CCIE certification. Before reading this book, it is important to have at least read the Sybex CCNA: Cisco Centified Network Associate Study Guide, Second Edition. You can take the CCNP tests in any order, but you should have passed the CCNA exam before pursuing your CCNP. Many questions in the Routing exam are built upon the CCNA material. However, we have done everything possible to make sure that you can pass the Routing exam by reading this book and practicing with Cisco routers.
The new Cisco certifications reach beyond the popular certifications, such as the MCSE and CNE, to provide you with an indispensable factor in understanding today's network-insight into the Cisco world of internetworking.
Cisco---A Brief History
A lot of readers may already be familiar with Cisco and what it does. However,those of you who are new to the field just coming in fresh from your MCSE, or maybe even with 1O or more years in the field but wishing to brush up on the new technology, may apprectate a little background on Cisco.
In the early 1980s, a married couple who worked in different computer departments at Stanford University started up cisco Systems (notice the small c). Their names are Len and Sandy Bosack. They were having trouble getting their individual systems to communtcate (like many married people), so in their living room they created a gateway server to make it easier for their disparate computers in two different departments to communicate using the IP protocol .
In 1984, Cisco Systems was founded with a small commercial gateway server product that changed networking forever. 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? But in 1992, the company name was changed to Cisco Systems, Inc.
The first product it marketed was called the Advanced Gateway Server(AGS). Then came the Mid-Range Gateway Server (MGS), the Compact Gateway Server (CGS), the Integrated cateway Server (IGS), and the AGS+. Cisco calls these "the old alphabet soup products."
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 Systems 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.
Cisco Systems' big picture is that it 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 imperative. Because Cisco Systems offers such a broad range of networking and Internet services and capabilities, users needing regular access to 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 are used to form information networks using the Cisco Internetworking Operating System (IOS) software. This software provides network services, paving the way for networked technical support and professional services to maintain and optimize all network operations.
Along with the Cisco IOS, one of the servtces Cisco created to help support the vast amount of hardware it has engineered is the Cisco Certified Internetworking Expert (CCIE) program, which was designed specifically to equip people to effectively manage the vast quantity of installed Cisco networks. The business plan is simple: If you want to sell more Cisco equipment and have more Cisco networks installed, ensure that the networks you installed run properly.
However, having a fabulous product line isn't all it takes to guarantee the huge success that Cisco enjoys-lots of companles with great products are now defunct. If you have complicated products designed to solve complicated 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 Networking, 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 reaects the demands of today's internetworking business environments.
Bunding upon the highly successful CCIE program, Cisco Career Certifications permit you to become certified at various levels of technical proficiency, spanning the disciplines of network design and support. So, whether you're beginning a career, changing careers. securing your present position, or seeking to refine and promote your position. this is the book for you!
Cisco's Installation and Suppon Cenifications
Cisco has created new certifications that will help you get the coveted CCIE. as well as aid prospective employers in measuring skill levels. 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 that 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?
Cisco Cenified Network Associate (CCNA) 2.O
The CCNA certification is the first certification in the new line of Cisco certifications and it is a precursor to all current Cisco certifications. With the new certification programs, Cisco has created a type of stepping-stone approach to CCIE cetification. Now, you can become a Cisco Certified Network Associate for the meager cost of the Sybex CCNA: Cisco Certified Network Associate Study Guide, Second Edition, plus e l00 ror the test. And you don't have to stop there-you can choose to continue with your studies and achteve a higher certification called the Cisco Certified Nework Professional (CCNP). Someone with a CCNP has all the skills and knowledge they need 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.
Cisco Cenified Network Professional (CCNP) 2.0
This new Cisco certification has opened up many opportunities for the individual wishing to become Cisco-certified but who is lacking the training, the expertise, or the bucks to pass the notorious and often failed two-day Cisco torture lab. The new Cisco certificattons will truly provide exciting new opportunities for the CNE and MCSE who just don't know how to advance to a higher level.
So, you're thinking, "Great, what do I do after I pass the CCNA exam?" Well. if you want to become a CCIE in Routing and Switching (the most popular certtfication), understand that there's more than one path to that much-cov-eted CCIE certification. The first way is to continue studying and become a Cisco Certified Network Professional (CCNP). That means four more tests, and the CCNA certification, to you.
The CCNP program will prepare you to understand and comprehensively tackle the internetworking issues of today and beyond-not limited to the Cisco world. You will undergo an immense metamorphosis, vastly your knowledge and skills through the process of obtaining alese certifications.
Remember that you don't need to be a CCNP or even a CCNA to take the CCIE lab, but to accomplish that, it's extremely helpful if you already have these certifications.
What Are the CCNP Certification Skills?
Cisco demands a certain level of proficiency for its CCNP certification. In addition to those required for the CCNA. these skills include the following:
· Installing. configuring, operating. and troubleshooting complex routed LAN, routed WAN, and switched LAN networks, and Dial Access Services.
· Understanding complex networks, such as IP, IGRP, IPX, Async Routing, 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. 1O, FDDI. and transparent and translational bridging.
To meet the Cisco Certified Network Professional requirements, you must be able to perform the following:
· Install and/or configure a network to increase bandwidth, quicken network response times. and improve reliability and quality of service.
· Maximize performance through campus LANs, routed WANs, and remote access.
· Improve network security.
· Create a global intranet.
· Provide access security to campus switches and routers.
· Provide increased switching and routing bandwidth-end-to-end resillency services.
· Provide custom queuing and routed priority services.
How Do You Become a CCNP?
After becoming a CCNA, the four exams you must take to get your CCNP are as follows:
Exam 640-503: Routing This exam continues to build on the fundamentals learned in the CCNA course.
