When will 128M not be enough?

Is there any research out there that tries to estimate how long it will be before BGP routers with 128M of RAM start to choke on the routing table? I know there are a lot of factors - the number of BGP peers, how much "other stuff" the router is doing, etc. - I'm really looking for a ballpark estimate, if one exists. I'm trying to convince someone NOT to use a Cisco 2650 for BGP multihoming, and my argument will, IMO, be a bit more effective if I can say "you'll need to replace it within X months/years"... -C --------------------------- Christopher A.
