BGP Growth projections

[Mark Radabaugh]

I'm looking for new core routers for a small ISP and having a hard time 
finding something appropriate and reasonably priced.   We don't have 
huge traffic levels (<1Gb) and are mostly running Ethernet interfaces to 
upstreams rather than legacy  interfaces (when did OC3 become legacy?).    

Lot's of choices for routers that can handle the existing BGP tables - 
but not so much in small platforms (1-10Gb traffic)  if you assume that 
IPv6 is going to explode the routing table in the next 5 years.    The 
manufacturers still seem to think low traffic routers don't need much 
memory or CPU. 

What projections are you using regarding the default free zone over the 
next 5 years when picking new hardware?
