As I said before, we hit a big preventing the ability to do this even if we wanted to. The impact is drop all traffic or permit all in that case.Hi Jared, I'm not confident you caught the implications of what I said. At the reciprocal peering link, you don't drop the spoofed traffic. You let it flow. You then charge a penalty when it turns out the peering traffic includes spoofed packets. The impact isn't drop or permit. It's dollars. Those who can't or won't control their customer links (where they trivially know what addresses are allowed) start to pay large amounts of money where they peer. More money than it takes to to properly implement customer-link filters so that they don't send spoofed packets to the peer. No new tech. No blocking. Just cashflow.
