GNS3: Graphical Network Simulator - Final Thoughts
(Page 4 of 4 )
During this article we mentioned that to get the most out of GNS3 you’re required to have a strong foundation in networking concepts and even have a deep interest in learning Dynagen commands, as well as reading the documentation of the networking devices with which you are experimenting, to find out the commands which they support, how to configure them, and do such and such with them.
O’Reilly Publishing has an amazing book titled Cisco IOS Cookbook. It covers some of the most common router configuration tasks such as configuring interfaces along with routing protocols, setting up backup links, implementing packet filters, handling the routine access control mechanisms, what to do in the case of DHCP and NTP services, and so forth. If CISCO-related activities are part of your life, then this book would help!
Furthermore, we’d suggest checking out some of the video tutorials from the GNS3 official website to see what the product is able to do in action. You may also find the tutorials from blindhog’s blog, or perhaps just search for videos related to GNS3 on YouTube—however, when doing the latter you’re going to find demos done for the sake of presentations rather than actual well-explained tutorials like the first two sources.
We truly think that once you get the hang of GNS3 you are going to really love this product. It is an amazing time-saver for system administrators as well as students studying for their CISCO certifications such as CCNA, CCNP, CCIE, CCIP, and the like. Emulators are always fun to experiment with. There’s nothing you can do wrong.
