What if I want to accomplish both getting reports for top source/destination AS 
as well as compare the traffic of each of our providers? I remember writing 
down each AS of our providers in CUFlow.cf and using CUGrapher.pl, I'm creating 
composite in and out traffic graphs of those four providers.. Given all of our 
routers configured with origin-as, does that mean I am displaying wrong graphs 
with our upstream providers?
