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?

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.
