| |
| Configuring PPP PAP AuthenticationNow we know how the ISDN link comes up (interesting traffic), and some scenarios that might cause the link to stay up, we need to look at ISDN authentication schemes. The two methods Cisco certification candidates must be familiar with are PAP and CHAP.Password Authentication Protocol (PAP) sends the username and password over the ISDN link in clear-text. Sending any passwords over any WAN link in clear-text is generally a bad idea, but it's important to know you have this option.Regarding both PAP and CHAP, it's a common misunderstanding that each side must authenticate the other. PAP and CHAP both support bidirectional and unidir (read full article) |

| The major reason I recommend getting your hands on real Cisco equipment rather than a simulator is that real Cisco routers give you the chance to practice and learn show and debug commands.The knowledge you acquire from debugs is invaluable. Frankly, it's this knowledge that puts you above the 'average†CCNA who doesn't have that hands-on experience. Watching debugs in action also gives you a head start on the CCNP. Since 90 - 95% of CCNAs go on to pursue the CCNP, it's a great idea to get started with debugs now.Don't make the mistake of waiting until you're studying for your CCNP and CCIE to start learning debugs and shows. The work you do for the CCNA is the fou (read full article) |

| Article Title :: Cisco Certification: Building Your Own Home Lab, Part I |
| |
| CCNAs and CCNA candidates hear it all the time: 'Get some hands-on experience'. From my personal experience climbing the Cisco certification ladder, I can tell you firsthand that there is no learning like hands-on learning. No simulator in the world is going to give you the experience you will get cabling and configuring your own routers.Whenever I mention this to one of my students, they always say it costs too much. The truth is, it is cheaper now to build your own CCNA and CCNP lab than it has ever been. The secret? Used routers.The word 'used' turns off a lot of people; not many of us buy used computers or used servers. Cisco routers, though, are robust; I perso (read full article) |

| Article Title :: Cisco Certification: Building Your Home Lab, Part II |
| |
| In the first part of this home lab tutorial, CCNA and CCNP candidates can see that there are a LOT of choices when it comes to what to buy to build your own Cisco practice lab.Having been there myself, I know it's confusing to decide how many routers or switches to buy, and what I need at the minimum to run labs and get some great hands-on practice. Let's take a look at some lab configurations and some other lab equipment you may need.A starter practice lab will consist of two Cisco routers and one switch, hopefully a 2950. This is a good way to get started. You will need to make sure that the routers you purchase have Ethernet ports, and at least one serial port. If p (read full article) |

You've got enough on your mind just keeping all that new information straight without worrying about what the testing experience will be like.You're not there to take the exam.

| Article Title :: Cisco Certification: A Survival Guide To The Cisco Cable Jungle |
| |
| One of the most confusing parts of beginning your Cisco studies is keeping all the cable types separate in your mind, and then remembering what they’re used for. This often occurs when a CCNA or CCNP candidate starts putting together their own home practice lab, and they suddenly realize that they have the equipment to run labs, but not the cables.With this in mind, here are some common Cisco cable types and their primary use.First, there’s the regular old “straight-through cable”, so named because the eight wires inside the cable go straight through the wire. While the wires may be twisted inside to reduce electromagnetic interference (EMI), the wire that’s con (read full article) |

| |
| When you're studying to pass the BSCI exam and earn your CCNP certification, you're going to be introduced to ISIS. ISIS and OSPF are both link-state protocols, but ISIS works quite differently from OSPF. You must master these details in order to earn your CCNP.
One of the major differences between OSPF and ISIS will be evident to you when you first begin your BSCI exam studies, and that is the terminology. ISIS uses terms that no other protocol you've studied to date uses, and learning these new terms is the first step to BSCI and CCNP exam success.
First off, what does "IS" stand for in "ISIS"? It stands for "Intermediate System", which sounds like a group of rout (read full article) |
