[c-nsp] Usage Billing w/ Netflow / Implementation Pitfalls

[Chris Riling]

Hi All,

     I know this has been asked thousands of times before, but I don't think
anyone has ever answered it in quite the same fasion. I'm thinking about
turning on netflow on my border routers (7606's with Sup32's / full routes);
Think I'll see any issues from turning on the exports? Also, specifically,
we're looking to see the ability to generate reports for say, a /22, and the
amount of transfer for each host in the /22 that has entered / exited our
network at the border (MRTG on the switchports isn't going to cut it). I've
heard that a lot of people use ntop for this sort of thing, but in the demo
I wasn't able to find anything that did exactly this, and I wanted to
consult the list before turning on Netflow at the border routers anyway.
I've also heard of people using stager for the report generation; can stager
do the same sort of thing?

Thanks,
Chris
