Route advertisements do not fit any existing model, since an advertisement affects all members of the system equally, no matter how far away they are from the advertisement.

Reread my email dated 4/17/2003 with subject of "selective auto-aggregation" I think you'll find I've already given some thought on proxy aggregation as better than prefix-filtering for maintaining connectivity while limitting the effects of someone else's deaggregation.
Sprint did that in 1994-95. Or at least threatened to do it when one ISP that now had been bought by a promsing local ISP decided not to aggregate. The Sprint's move was enough to force that ISP to aggregate. Alex
