	Let's look at a hypothetical situation. ISP1 peers at MAE-E and 
buys transit from MCI there. Now they ask Sprint to peer with them. Let's 
look at how they reach sites on the west coast.

	Without peering, MCI gives the packets to Sprint at MAE-East and 
Sprint returns packets to MCI at some west coast nap. That is, MCI and 
Sprint share the coast-to-coast traffic.

	With peering, Sprint must take the packets all the to MAE-E as it 
has a shorter AS path. All the coast-to-coast cost is borne by Sprint.

	Do you get that? Now do you understand the 3 NAP rule?
