Read your peering contract with the other ISP. It should cover what to do
if this happens.
What? you don't have a peering contract with the other ISP. Well I guess
there is no requirement to keep the peering session established if the
peer does stuff you don't want on your network.
If it hurts when you do something, why do you keep doing it?
