I suspect if we do this, when things 'come back up', we'll be under 200k. -- "Fergie", a.k.a. Paul Ferguson Engineering Architecture for the Internet fergdawg(at)netzero.net ferg's tech blog: http://fergdawg.blogspot.com/

You could always send those networks a bill for your next BGP-speaking core upgrade. TCAM entries are expensive y'know.
From what I've seen here and other lists there seems to be a good financial reason now to aggregate thanks to implementation choices by vendors and purchasing choices by providers.

We got hit by this a couple of months back. We had held out from doing policy based routing for many many years, but the sheer number of small routes grew to the point where we couldn't handle the full routing table and run DCEF at the same time. We were kind of forced into it. Last I knew, we accepted anything down to a /24 for Arin allocations, and dropped everything below the minimum allocation size for all the other registries. So far, it has been working great for us, and we were able to buy another year or two out of our Cisco gear. But I can see the end of the line coming and I believe we are going to need to replace our core routers sooner rather than later.
