HOW DID I DO THE STARWARS TRACEROUTE?

How did I do the Starwars Traceroute?

Bored, and in a blizzard in Boston; I was inspired by my IRC friend 'Plazma' constantly making fun of my reverse dns of scrye.net, I came up with this pretty neat hack.

It is accomplished using many vrfs on (2) Cisco 1841s. For those less technical, VRFs are essentially private routing tables similar to a VPN. When a packet destined to 216.81.59.173 (AKA obiwan.scrye.net) hits my main gateway, I forward it onto the first VRF on the "ASIDE" router on 206.214.254.1. That router then has a specific route for 216.81.59.173 to 206.214.254.6, which resides on a different VRF on the "BSIDE" router. It then has a similar set up which points it at 206.214.254.9 which lives in another VPN on "ASIDE" router. All packets are returned using a default route pointing at the global routing table. This was by design so the packets TTL expiration did not have to return fully through the VRF Maze. I am a consultant to Epik Networks who let me use the Reverse DNS for an unused /24, and I used PowerDNS to update all of the entries through mysql. This took about 30 minutes to figure out how to do it, and about 90 minutes to implement. All VRFs and DNS were generated by a PHP script.
