| Article Title :: Cisco CCNA Certification Exam Tutorial: Configuring And Troubleshooting VTP |
| |
| Not only is your CCNA exam going to have questions on VLAN trunking protocol, almost any network that has more than one VLAN is going to have VTP running. Whether you're planning on passing the CCNA exam or just brushing up on your networking skills, this VTP tutorial will help you learn the basics of this important protocol.VTP allows switches to advertise VLAN information between other members of the same VTP domain. VTP allows a consistent view of the switched network across all switches. When a VLAN is created on one switch in a VTP server, all other VTP devices in the domain are notified of that VLAN’s existence. VTP servers will know about every VLAN, even VLANs that h (read full article) |

| Article Title :: Cisco CCNP / BSCI Exam Tutorial: Ten IP Routing Details You Must Know! |
| |
| To pass the BSCI exam and earn your CCNP, you've got to keep a lot of details in mind. It's easy to overlook the "simpler" protocols and services such as static routing and distance vector protocols. With this in mind, here's a quick review of some details you should know for success in the exam room and real-world networks!When packets need to be routed, the routing table is parsed for the longest prefix match if multiple paths exist with the same prefix length, the route with the lowest AD is preferred. If there are still multiple valid paths, equal-cost load-sharing goes into effect.The ip route command is used to create static routes the command ip route 0.0.0.0 0.0.0.0 (read full article) |

| Article Title :: Cisco CCNP / BCMSN Exam Tutorial: Changing The Active Router In HSRP |
| |
| To pass the BCMSN exam and earn your CCNP certification, you've got to know HSRP inside and out. While the operation and basic commands of HSRP are pretty simple, there are some important details that are easily overlooked but are vital in getting HSRP to work the way you want it to. Let's take a look at using the priority command correctly on both the exam and in production networks.A key value in the show standby command is the priority. The default is 100, and the router with the highest priority will be the primary HSRP router. We'll raise the default priority on R2 and see the results. R3 is currently the Active router and R2 the standby, so let's raise the priority on R2 (read full article) |

| Article Title :: MCSE Certification: A Leg Up On Your Co-Workers |
| |
| Most people in this world would not be able to tell you what an MCSE certification is. Making it longer may confuse people even more; it stands for Microsoft Certified Systems Engineer. Just studying to take the test is a trial and the test itself can be difficult, not to mention expensive. It can give you a benefit that a lot of computer techs in the world don't have: a certification from Microsoft and spiffy initials to put after your name. The test is comprehensive and challenging. It has four networking tests, one client operating system test, a design test and a test over an elective.According to the Microsoft website, there are benefits that go along with an MCSE certifi (read full article) |

| Article Title :: Cisco CCNP Certification / BCMSN Exam Tutorial: The HSRP MAC Address |
| |
| To pass the BCMSN exam and earn your CCNP, you've got to know HSRP inside and out! Part of that is knowing how the MAC address of the virtual router is derived, and another part is knowing how to change this address. We'll look at both features in this tutorial.
We've got two routers on a segment running HSRP, so first we need to find out what the MAC address of the HSRP virtual router is. The show command for HSRP is show standby, and it's the first command you should run while configuring and troubleshooting HSRP. Let's run it on both routers and compare results.

| Article Title :: Cisco CCNP Certification / BSCI Exam Tutorial: An Introduction To BGP |
| |
| When you're studying for the BSCI exam on the way to earning your CCNP certification, it's safe to say that BGP is like nothing you’ve studied to this point. BGP is an external routing protocol used primarily by Internet Service Providers (ISPs). Unless you work for an ISP today or in the future, you may have little or no prior exposure to BGP. Understanding BGP is a great addition to your skill set – and you have to know the basics well to pass the BSCI exam.
Note that I said “the basics”. BGP is a very complex protocol, and when you pursue your CCIE, you’ll see what I’m talking about. As with all things Cisco, though, when broken down into smaller pieces, BGP becom (read full article) |

| Part of studying for CCNA exam success is keeping all these new commands straight in your head! And let's face it, there are a lot of commands you need to know in order to pass the CCNA exam and earn that certification. Here's a review of some very important distance vector and static routing commands you need to know, along with their proper usage and console output.
Bandwidth
IGRP makes a default assumption that any Serial interface running IGRP is connected to a T1 line, which runs at 1544 KBPS. With equal-cost load-balancing enabled by default, this may be an undesirable assumption.
To alter IGRP’s assumption, use the bandwidth command on the serial int (read full article) |
