GNS3 you can, they have a fairly well documented JSON based API that you

We have 9 ASR's so I don't think it would be too hard to host them in the GNS3

supported, which is where Cisco IOSv comes in, hoping it could be configured in
a way to act very closely like our deployed hardware. I'm not

Snake topology does conserve IXIA/Spirent ports but will not allow you
to test
I've been using network simulation well before GNS3 was around using
dynamips - and even when GNS3 came along it was still not good -since it
just couldn't handle the scale (~40nodes) (not on my compute resources at
that time anyways).
And similarly nowadays in the era of proper HW simulation

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.

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)
I use the community free version… lots

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.

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,
The alternative or complementary approach is something like batfish[1], for
validation vs. emulation.

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

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
