You can't do proxy aggrigation without consent!!! You WILL create policy violations as well as destablizing global routing. Forget any concept of 'forced proxy aggregation'!!!!
Bullshit. If you have networks in the same AS, your service provider or peers will aggregate your networks. Policy is done ONLY on a per-AS basis. Those are the rules in this new world order, and if you don't like it, may I suggest that you try to find other folks to peer with who would rather roll over and die than violate your policy.
While I strongly agree that we have to aggregate or we will all die horribly painful deaths (or something like that), perhaps I'm fundamentally confused here. IIJ has a single policy, we have a single AS, but we have this problem that a large network to which some of our customers want to talk makes determinations based on network numbers. We can aggregate all of 202.32/16, but we either have to lie to the NSF and claim all customers in that block are AUP compliant or all the customers in that block can't get to the NSFnet. Therefore, we have to break 202.32/16 into pieces and some service provider up the wire may proxy aggregate for us. Or have I missed something obvious? Thanks, -drc
