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 [...]
CCNP exam success, particularly on the BSCI exam, demands you understand the details of route summarization. This skill not only requires that you have a comfort level with binary conversions, but you have to know how and where to apply route summarization with each individual protocol.
You also have to know the “side effects” of [...]
To pass the BSCI exam and move one step closer to CCNP certification success, you’ve got to know how and when to use debug commands to troubleshoot and verify network operations. While you should never practice debug commands on a production network, it’s important to get some hands-on experience with them and not rely on [...]
To pass the CCNA exam, you’ve got to create a study plan. Part of that plan is scheduling your study time, and making that study time count.
You’ve scheduled your exam you’ve created a document to track your study time you’ve planned exactly when you’re going to study. Now the plan must be carried out, without [...]
To pass the BSCI exam and earn your CCNP certification, you’ve got to master the (many) details of OSPF. You might have thought there were quite a few OSPF details in your CCNA studies, but you’ll now build on that foundation on the way to earning your CCNP.
One such detail is the role of the [...]
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 [...]
When you begin your CCNA studies, you get hit with a lot of different networking terms right away that you might not be familiar with. What makes it a little more confusing is that a lot of these terms sound a lot alike. Here, we’re going to discuss the differences between broadcasts, multicasts, and unicasts [...]
One of the first things you do when you start studying for the CCNA exam is memorizing a list of port numbers and the protocols that run on those ports. If you’re an experienced networker, you know most of the protocols that are mentioned - DNS, DHCP, FTP, SMTP, and so on. But there’s one [...]
When studying for your BSCI exam for the CCNP, you get your first taste of BGP. One of the major differences between BGP and the other protocols you’ve studied to date is that BGP uses attributes to describe paths, and to influence the selection of one path over the other.
In this free tutorial, we’re [...]
BECNs and FECNs aren’t just important to know for your Cisco CCNA and CCNP certification exams - they’re an important part of detecting congestion on a Frame Relay network and allowing the network to dynamically adjust its transmission rate when congestion is encountered.
The Forward Explicit Congestion Notification (FECN, pronounced “feckon”) bit is set to zero [...]
