Certainly in principle it can, though that is not in the current proposal. The basic idea is to suppress installing routes into the FIB when there is a "virtual aggregate" that you can tunnel to instead. I remember we discussed this in San Jose NANOG, but I forget the details. Can you remind me? PF

There has been a lively discussion of this on the IDR mailing list,includinga suggestion that FIB reduction is more important for lower tier ISPs(tier2, tier 3...) than for tier 1 ISPs. Unfortunately I don't think thatpeoplefrom smaller ISPs pay much attention to the IDR mailing list, so theyare notbeing represented in this discussion. So I'm looking for input from folks who think that FIB reductionhelps them,so as to better understand their requirements. Any help is much appreciated. Thanks, PF
