Tool for monitoring BGP traffic

Answered Question
Aug 19th, 2008


I've two routers dual-homed with two ISP.

I'm interested in a tool (OPEN-SOURCE) for monitoring and accounting data passing through the routers and going to ISP. Which traffic goes through ISP 1 and which traffic goes through ISP 2?

That is I'm interested in tuning the traffic with BGP attributes (weight, preference and so on) in order to do load balancing between two ISP.

Thank you.

Best regards.


I have this problem too.

I think Cisco IOS Netflow will provide the accounting , but you require Open Source !!!
