By John Oden

So you are reviewing some practice test questions as you prepare for a Cisco exam and you come across a scenario that states something like, “…and all the routers in the topology are manufactured by Cisco.” You immediately shift your focus and begin to examine the available choices, scanning for anything that has to do with the Enhanced Interior Gateway Routing Protocol (EIGRP). We’ve all done that, right?

How to use NetSim Network Simulator | New Demo Labs Available

Posted by Kelly Mansfield on Jan 31, 2013 9:12:00 AM

You asked, we answered! When you asked about creating your own topologies in NetSim, we listened and have now released labs to help you do just that. The two new Demo labs we released allow you to work through the steps to create a topology and then configure it. You can do so much more in this lab than simply evaluate NetSim – you can create, configure, modify, and examine everything within your simulated network. You can see the steps in the Demo labs performed in the videos below.

A Case Study on EIGRP Graceful Shutdown

Posted by Kelson Lawrence on Feb 8, 2011 10:25:00 AM

By Andrew Messier

The topology for this study consists of two routers connected on a LAN. FastEthernet 0/0 on Router1 connects to FastEthernet 0/0 on Router2. Full connectivity exists between both routers, and Enhanced Interior Gateway Routing Protocol (EIGRP) using Autonomous System (AS) 100 is configured to run on both FastEthernet ports. Below is sample configuration for this setup:
