Your BGP config with ISP2 is probably unideal. This has lead to packets coming in via ISP2 despite the fact you prefer to use ISP1. Often, people only do AS Prepend to alter traffic patterns. However, if a packet finds it's way to your directly connected ISP, an AS Prepend is not enough. It will be sent to you based on local preference. Setting appropriate communities with your ISP can often override this preference so they will send the packet towards your ISP1 instead of direct. Strangely, BGP actually works without issues. The only issue is with
statically routed ranges.
