Viability of GNS3 network simulation for testing features/configurations.

[Ryland Kremeier <rkremeier () barryelectric com>]

Hello,

I'm currently in the process of setting up a near identical network to our own in GNS3 for testing purposes. Has anyone 
here tried this before to any success? We need to buy the Cisco IOSv image to continue with the sim so I figured I 
would inquire here first before diving in.

All info is appreciated,
