This is simply accomodated by mutliplying the maximum utilisation figure by 0.75 for every layer of hierarchy or aggregation in the network. So for a 3 layer network plus another layer for international aggregation the maximum utilisation falls to 0.75^4=0.316 == 32%. This is the theoritical maximum address utilisation that can be achieved without breaking aggregates. I think we should penalize anyone who gets a better address utilisation than this because they are obviously announcing more routes than they need to ;-) Peter.
