Re: Viability of GNS3 network simulation for testing features/configurations.

[Tom Beecher <beecher () beecher cc>]

GNS3 can do a heck of a lot, and the price is definitely right.

I have used it extensively for initial fleshing out of designs or ideas,
protocol nerding, automation interaction testing, etc. There certainly
other tools out there, but being able to visually draw a topology out,
connect the dots, and have an environment to test in about 10 minutes is
very nice. There is an API you can hook into to do some of that for you if
you are so inclined, but that would depend on your use case and resources.
For how I've used it, never been required.

Some of the VMs from vendors can be pretty CPU and/or RAM intensive, so
I've had the best experience running them all on a dedicated server, not
locally. Again, use case dependent. For code testing I would always run the
test set on hardware as well for likely obvious reasons.

If you really get into the weeds with it you can do quite a lot.
