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
I did this at my current company with also using VM Palo Alto.
Greeting of testing out a plan to make sure its insane.
The key it keeping its all up todate down to the firmware version (I know
its not possible for some because virtual)
The things this wont find are hardware related faults or iss
This also depends on your scale. If you have lots of routers, you would end up
with lots of compute to run the VM instances. If you get the compute (which is
cheap comparing to actual network hardware), you would need a "cloud
orchestration” tool and a a system to connections from host to host
The alternative or complementary approach is something like batfish[1], for
validation vs. emulation.

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,

Totally agree with Tom here. It's going to work really well for most
things. But if you're testing code for bugs you NEED to do it on the same
hardware you have in your environment in an actual lab.

I’ve used GNS3 some years ago for a lot of simulation and testing. But, I’m
blown away at how much more I like EVE-NG (emulated virtual environment
next-gen)

EVE-NG is also really good. Just an FYI, GNS3 went through a major refresh
about 18 months ago or so and it's so much better now. Either way, you can't go
wrong with GNS3 or EVE-NG.
