I have a particular vendor whose ISP is dropping ~50% of my network traffic to them. The problem is 7 hops into AT&T's network. This vendor claims the issue is my ISP. It looks more likely that AT&T is influencing the return routing in an attempt to load balance and dropping half of my packets into the bit bucket. My ISP agrees this is the case. My vendor is very problematic and is still pointing the finger at me and my ISP.
I would totally agree if the problem was with my ISP.
I did do this originally to prove that my ISP was not the root cause of the traffic loss. Every step in the path is good until the 7th hop into the AT&T network (not my ISP). So it appears to me that on that particular device the return path is trying to load balance on two links and one of the return paths has a bad list of ASNs. Resulting in the approx 50% loss of traffic.
The vendor that resides on the AT&T network is not very technical and I need to provide some type of proof that the issue is at their ISP and not mine. The question I have is how to I provide that data so that they can involve their ISP to correct this issue?
