Just another thing here, Cisco itself has some internal simulator stuff.
Just like dynamips, people use it for studies since its suppose to be really
good better than dynamips. So I am sure as long as it is educational it
shouldn't be a problem. I don't get it why are we even talking about this, I
am not going to stop using it.
