John Scudder (Juniper) had a presentation on BGP and FIB/RIB scaling at NANOG in Toronto a year or so back (shortly after the IAB Workshop): <http://www.nanog.org/mtg-0702/presentations/fib-scudder.pdf> His last slide (URL above) is directly on-topic and says (quote): We can throw hardware at FIB scaling for at least the next decade or so, with existing technology • Several bigFIB boxes shipping now This provides time to research routing/addressing architectures • Really don’t want to build Internet on a R/A architecture that was hacked up quick under deadline pressure BGPfree core can protect core (“P”) router FIBs • Deployed today If one believes that, and following Brian's logic above, then a first-class architectural approach for only IPv6 ought to be sufficient/acceptable as a Routing RG output. What do the big router implementers on this list think about the question of when we will hit a "catastrophic" scaling limit ?
