I am doing some research on NetFlow and wanted to ask you guys a few things:
How are you using NetFlow? For what purposes? Billing? Security? Do you have NetFlow enabled on all your routers? Do you enable it on all the interfaces or just on the external/internal interface? Do you utilize any tool to stitch the NetFlows back together? Why would you do that?
I guess you can tell that I was never exposed to NetFlow in the ISP world. Any answers or comments are really appreciated.
Thanks
