I was reading David Bombal's "Cool IOS Commands Networking Tips Newsletter*" the other day and in it he has a link to a video showing you how to use ExamDiff to compare configurations. I had never heard of ExamDiff before and so decided to compare it to the file comparison tool that I use. I must say that ExamDiff is a very nice little tool. It has a lot of sophisticated functions and in my opinion it displays the differences in configurations nice and clearly, which is a must when you are scrolling through hundreds of lines of configuration at 3 in the morning and your eyes are stinging like hell. My only problem with it is that you need to upgrade to ExamDiff Pro at a cost to be able to compare directories.
Comparing directories of configuration files is a feature that is very important to me. I use this feature to download all the configuration files I am working on before a change and then download them after a change and compare directories to see the differences. So for the moment I will keep using Microsoft's WinDiff which allows me to compare directories and is still free. On the downside it has a lot more of a basic feel to it compared to ExamDiff (see below). Does anyone else have any configuration comparing utilities that they can recommend?

David Bombal is also the guy who produces the CCIE command memorizer and I was thinking of getting it. I have seen a couple of blogs asking people for their opinions on it, so I will join the club has anyone else used this tool and if so what did they think?
