Yes, you are correct I have decided to go for my CCIE:Security and need some practice before the lab exam.
My only choices for multi-homing at home are T1s/DS3s... And cable. I already have a 3-T1 setup where the Class C block is homed now. This is my main business line and hosts my DNS, Web, Mail servers and VPN connections. The ISP I use is has punched a hole in their Class B to allow my Class C block to leak through. At some point I may get a business class cable line. But since I do not know if what I am doing will violate Roadrunner's AUP and/or cause them to disconnect me, I decided to go with the $29.95 special. My ISP already peers with Level3, and Roadrunner peers with Level3 (AS3356) and AOL (AS 1668). My goal is to block all routes via Roadrunner/Level3 and force all inbound and outbound traffic via Roadrunner to go through AS 1668 only. Edward W.

You have a real network with routers, T1 lines, all that jazz. And you'd like to multihome with a cable modem?
