Wouldn't a reasonable approach be to take the sum of a 6500/msfc2 and a 2851, and assume that the routing computation could be offloaded?
The difficulty I have with this discussion is that the cost per prefix is zero until you need to change eigenstate, where there's a big cost, and then it goes back to zero again. Because this isn't really all that new a problem, most vendors try not to make devices which have no headroom at all - so kit in the lower category seems to be qualitatively different. -David Joe Greco wrote: >> On Mon, 21 Jan 2008, Joe Greco wrote: >> > Given that the 3750 is not acceptable, then what exactly would you propose >> > for a 48 port multigigabit router, capable of wirespeed, that does /not/ >> > hold a 300K+ prefix table?
