There are a lot of switches, routers, and firewalls out there that, although not the latest, are still quite functional. And they're available inexpensively or even free. Buying used gear is most often technically just as illegal as grabbing the images from some file sharing site because the licenses are not transferable. That said, I carefully reviewed the license for the software that makes my car work and it's not transferable either so in some cases buying a used car is just as illegal (technically -- no court would ever entertain that you did something illegal with regard to software licensing in buying a used car).

I expect the automobile manufacturer's lawyer wasn't a software licensing specialist and used a lot of boiler plate text from somewhere else without actually realizing the real implications. Of course there are dozens of Cisco re-sellers that sell used gear and those that do it the official Cisco way (sending the equipment back to Cisco for official re-licensing and charging again for the licensing) are obviously at a serious pricing disadvantage. Remove Internet Low-mic Utility Tool. I don't know of any cases of Cisco taking legal action to enforce their intellectual property rights against a re-seller and I'd be very surprised if they took exception to someone using their software in a 'virtual' GNS3 environment. If the software images do come from anywhere other than the official Cisco software repository (including preinstalled on used gear) you really need to check the MD5 signature against the official Cisco version.

Aug 27, 2016 - After some years, it's time again to prepare for my next CCNP re-certification. I was pleasantly surprised that running full-featured Cisco L2 images is now made entirely possible with the new 'IOS on Unix (IOU)' function on GNS3. I documented my new setup here according to the GNS3 v1.5.2 running on a. How to Integrate Cisco IOU with GNS3. Actual IOS images that run on the real Cisco routers are. I can’t give you the direct links to download it.

There have been reports of compromised IOS images making the rounds. I wonder what does harm and what does good from Cisco's perspective. Does Cisco come down hard on the little guy trying to get his CCNA? That little guy is going to pay for his CCNA (and maybe a CCNP) and chances are he'll be drinking at least some of the Cisco kool-aid for the rest of his networking life.

I'll bet Cisco bank on getting more sales from 'on-boarding' Cisco acolytes than they would if they were seen to be harsh with people who, at the end of the day are likely to recommend and use MORE Cisco kit and not less. The same goes for the 'un-official' re-sellers. At the end of the day if a business (or whatever) buys a bit of Cisco gear, who is going to be making money?
