Simulating a network

I enrolled in a CCNP course today. I'd like to run some of the assignments at home, but I don't have any suitable hardware laying around. Does any of you know of some software to simulate a Cisco router, or even a complete network of them? Lab-hours are limited, sadly. I'd like to do some stuff at home, if I can. Ideas, suggestions?

This might be of some help Guus:

Hi

In addition to the previous link, I strongly recommend boson[1].
It can be downloaded via a redirect[2].

It's a dream!

Cheers.
