Since I do mostly content delivery I've been playing with this heavily for
the past four years. I use route maps with 3 tiered structured weights and
MEDs and pay special attention to major destinations such as 1239, 701,
7018, and some of the other transit providers (can't give away all my
secrets!). If you pay attention, you can even combine this with route
performance for optimal access. Be sure to use a real time monitor to track
the changes as they occur or you can accidentally slam a pipe. After a
while, you'll get a real feel of how to keep things steady.

:: I want to take the same IP ranges I have defined in my
:: access lists for
:: advertised routes and match them up with traffic as it goes
:: out so basically
:: my virtual load balancing will work on outbound traffic as
