1). Cisco CCNA Certification Exam Tutorial: Variance And Unequal Cost Load Balancing
To pass the CCNA exam, you've got to know how to work with IGRP and EIGRP unequal-cost load balancing. You may not see much IGRP in production networks anymore, but you'll see a lot of EIGRP, and part of fine-tuning your EIGRP network is making sure that all paths are in use while allowing for varying bandwidth rates.
Using the variance command is the easy part - it's getting the metric that's the hard part with IGRP.

3). Cisco CCNA / CCNP Home Lab Setup: How To Configure Reverse Telnet
Occasionally, during your CCNA and CCNP studies, you'll run into a term that just doesn't quite make sense to you. (Okay, more than occasionally!) One such term is "reverse telnet". As a Cisco certification candidate, you know that telnet is simply a protocol that allows you to remotely connect to a networking device such as a router or switch. But.

4). Cisco CCNA / CCNP Home Lab Tutorial: Configuring An Access Server
As your CCNA / CCNP home lab expands, an access server such as the Cisco 2509 or 2511 is one of the best investments you can make. In this article, we'll look at the basic configuration for an access server and discuss how to connect to the other routers and switches in your pod through the AS.
Here's part of a configuration from one of my access servers:
ip host FRS 2006 100.

5). Cisco CCNA Certification: Defining Broadcast Domains
When you're studying to pass the CCNA exam and earn your certification, you're introduced to a great many terms that are either totally new to you or seem familiar, but you're not quite sure what they are. The term "broadcast domain" falls into the latter category for many CCNA candidates.
A broadcast domain is simply the group of end hosts that will receive a broadcast sent out by a given host.

6). Passing Your CCNA and CCNP: Configuring And Troubleshooting Router-On-A-Stick
For CCNA and CCNP candidates, it's hard not to laugh the first time you hear the phrase "router on a stick". Let's face it, that's a pretty silly term. But as those who have passed the CCNA and CCNP exams know, this is a vital exam topic that you must know how to configure and troubleshoot.
Basic Cisco theory states that for hosts in different VLANs to communicate, a Layer 3 device must be involved to handle the routing between the VLANs.

8). Cisco CCNA Exam Tutorial: Loopback Interfaces
As a CCNA candidate, you most likely have some background in PC hardware and workstation support. If so, you're already familiar with loopback interfaces, particularly 127.0.0.1, the loopback address assigned to a PC.
When you're learning all about the different physical interfaces for your CCNA exam - serial, ethernet, and BRI, among others - there's one logical interface you need to know about, and that is - you guessed it! - the loopback interface.

9). Cisco CCNA Exam Tutorial: Configuring Standard Access Lists
Access Control Lists (ACLs) allow a router to permit or deny packets based on a variety of criteria. The ACL is configured in global mode, but is applied at the interface level. An ACL does not take effect until it is expressly applied to an interface with the ip access-group command. Packets can be filtered as they enter or exit an interface.
If a packet enters or exits an interface with an ACL applied, the packet is compared against the criteria of the ACL.

10). Cisco CCNA Certification Exam Tutorial: Configuring Dialer Profiles
The most common method of configuring ISDN is with dialer maps, but dial information can also be configured on a logical interface. To pass the CCNA exam, you must know how to configure and troubleshoot both dialer maps and dialer profiles.
Dialer Profiles allow different dialing information to be configured onto logical interfaces. The logical interfaces may have different dialing destinations, different remote router names, etc.

11). Cisco CCNA / CCNP Certification Exam Tutorial: ISDN And Multilink PPP
ISDN is a huge topic on both your Cisco CCNA and BCRAN CCNP exams. While many ISDN topics seem straightforward, it’s the details that make the difference in the exam room and working with ISDN in production networks. Configuring and troubleshooting multilink PPP is just one of the skills you’ll need to pass both of these demanding exams.
With BRI, we've got two B-channels to carry data, and both of them have a 64-kbps capacity.

12). Cisco CCNA Certification: How And Why Switches Trunk
Your CCNA studies are going to include quite a bit of information about switches, and for good reason. if you don't understand basic switching theory, you can't configure and troubleshoot Cisco switches, either on the CCNA exam or in the real world. That goes double for trunking!
Trunking is simply enabling two or more switches to communicate and send frames to each other for transmission to remote hosts.

13). Cisco CCNA / CCNP Home Lab Tutorial: A Guide To Cable Types
When you're putting your CCNA and/or CCNP home lab together, you're not just buying routers and switches you're creating a blueprint for success. There is no better way to learn about how real Cisco routers and switches work than to work with the real thing!
Of course, it's not enough to just get the routers and switches you've got to have the right cables and other devices to allow them to communicate.

14). Cisco CCNA / CCNP Home Labs: Developing Troubleshooting Skills
CCNA / CCNP candidates are going to be drilled by Cisco when it comes to troubleshooting questions. You're going to have to be able to analyze configurations to see what the problem is (and if there is a problem in the first place), determine the meaning of different debug outputs, and show the ability not just to configure a router or switch, but troubleshoot one.
