The big question is, of course, whether to upgrade a 6500 and keep it on
life support, or bite the bullet and go for a whole new box.  How much time
a -3bxl and careful filtering will buy you does depend heavily on where in
the Internet you are - but I'm willing to bet that a good number of sites
will go for the fork lift upgrade because there are *other* pressing things
coming up that the 6500 won't do either.

With a 3bxl, you won't need careful filtering. All the lower Sups top out at or slightly below 256k routes. IIRC, the 3bxl claims to support 1M ipv4 routes. Anyone else care to guess at how far off 235k routes is?

I'll concede that Jon is at least partially right - *somebody* is going to
be selling gear... ;)

Yeah...I posted recently on cisco-nsp that I think cisco's making a huge mistake not producing a Sup32-3bxl. When the Sup2 can't cope with "full routes" anymore, I suspect the Sup720-3bxl will already have been obsoleted by some higher end Sup. Then networks that would have bought Sup32-3bxl's for the route capacity, and don't really need the traffic capacity of the Sup720-3bxl will snap up Sup720-3bxl (and the required fan2s and power supplies) off the used market while bigger/richer networks upgrade to the Sup720-3bxl replacement.
