BGP
From Telecomix Crypto Munitions Bureau
There are mainly two software programs that you can use to build your BGP router: Quagga and OpenBGPD.
[edit] Darknets running BGP
BGP informs all other BGP nodes about how they are connected, in detail. It is thus possible to get a map of the network by joining it and setting up your own BGP router within it. This is not a security breach, but a feature. Because of this feature, TCMB has discontinued its research of BGP. It might be a better idea to use RIP or some other crappy and old routing protocol to hide the fine details of the network configuration.
There exists mainly three publicly reachable darknets that use BGP: AnoNet, AnoNet2 and Darknet conglomeration. Use google.
