Course Introduction


Welcome to our introductory Nugget on Cisco routing and switching troubleshooting mastery. In this Nugget, I'm going to go ahead and set up this entire course for you. Let's get started. This is indeed a very unique course for CBT Nuggets. And it all starts out very uniquely because it's going to be a dual instructor course.


That's right, you will hear from myself, Anthony Sequeira, and my dear friend Keith Barker throughout the Nuggets of this particular course. We'll both be bringing our opinions, our expertise to the various content areas that we move through in this exciting event.


Now, something else that's very unique about this course is the fact that it will focus on various levels of Cisco certification. As a matter of fact, within the first couple of moments of each Nugget, we will show you this little chart here. And we will literally tick off the boxes that will be dealt with in that particular Nugget.


So for example, if a topic deals with-- oh, let's say spanning tree protocol, and this is relevant from a CCNA to CCIE level, we will indeed indicate that. Now, when Keith and I were designing the course, we really said we wanted a good solid mix of both theory and practical applications in this course.


So that's what we really, really strived to do. In every single Nugget, as a matter of fact, you'll get a good dose of theory. You'll also get a good dose of practical command-line examples of real-world troubleshooting scenarios and problems. We are addressing both the real-world things that we could encounter in a network.


And of course, we are going to cover certification-based and certification favorite areas of troubleshooting. Now, what is our overall content? Well, it's core R and S. That's right, in order to make this a manageable size and a course you could get through in the typical amount of CBT Nuggets course time, we did confine this to core routing and switching.


So what you're going to see is us beginning with a wide variety of core layer 2 topics, things like VLANs; trunking; VLAN Trunking Protocol; Spanning Tree Protocol; EtherChannel technologies; from the wide area network perspective, frame relay; and the Point-to-Point Protocol.


Then we'll move to core layer 3 protocols like RIP version 2, EIGRP, OSPF, and BGP. We'll talk about generic routing encapsulation and policy-based routing. And then we'll wrap it up with redistribution. So let me just take a moment and tell you what troubleshooting topics you might find in the CCIE R and S practical lab exam that we tabled for other troubleshooting series so that we could really give and dedicate time to them.


Things like network security, multicast, performance routing-- these topics are certainly important in the scope of the CCIE routing and switching practical. But we really table them so that we could focus in this course on the core of routing and switching.


Another one just came to mind-- MPLS. Obviously, the topic area of MPLS-- this is something we could dedicate an entire CBT Nuggets course on. So Keith and I realized that we wanted to give amazing focus to the core layer 2, layer 3, and redistribution topics.


So that's what you're going to find in these 20 Nuggets that make up this particular course. So are you ready? I know Keith and I are ready. Please join us in the very first Nugget of true content where we take a look at the art of VLAN troubleshooting.


I hope this has been informative for you. And I'd like to thank you for viewing.
