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 like some form of overlay networking. <div class=""><br class=""></div><div class="">GNS3 would do a good job, but for something with a bit more orchestration APIs.

Yes, you would miss out on all the hardware bugs, hardware adaption layer issues and maybe a scale issue or two, but with enough instances, route generators and maybe even some application (some of these things can even forward traffic), you could discover 90% of things that can go wrong. </div><div class=""><br class=""></div><div class="">And you get the flexibility of downloading evaluation images of all kinds of things, so maybe you can avoid spending any money. </div><div class=""><br class=""></div><div class="">Yan</div><div class=""><br class=""><div class=""><br class=""></div><div class=""><br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Oct 16, 2019, at 12:03 PM, Jason Kuehl <<a href="mailto:jason.w.kuehl@gmail.com" class="">jason.w.kuehl@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">I did this at my current company with also using VM Palo Alto.<div class=""><br class=""></div><div class="">Greeting of testing out a plan to make sure its insane. </div><div class=""><br class=""></div><div class="">The key it keeping its all up todate down to the firmware version (I know its not possible for some because virtual) </div><div class=""><br class=""></div><div class="">The things this wont find are hardware related faults or issues.</div></div><br class=""><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Oct 16, 2019 at 11:52 AM Ryland Kremeier <<a href="mailto:rkremeier@barryelectric.com" class="">rkremeier@barryelectric.com</a>> wrote:<br class=""></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
