XORP: eXtensible Open Router Platform

For several years now, I've been looking for a good open-source router distribution. Smoothwall comes close, but it's a little simplistic for a good Cisco router replacement. Now, I don't know why I've not heard of it up until now, but here's what sounds like a good option: XORP. I downloaded the LiveCD and I plan to use it on my router box here at home. I hope it's good.
