There are at least 2 problems to be addressed (given that you believe 'too many routes will crush the dfz routers')... both number of routes and speed/number of updates. So, adding more MEMORY (pick your type DRAM/SRAM/bah) is only solving one of the problems. Additionally, most moderm DFZ-placed platforms aren't necessarily 'RAM' limited, some of the limits exist in hardware forwarding elements (TCAM/CAM/ASIC systems). Anyway, Suresh's followup has a decent info as well, you might locate the RRG and RAM/RAWs working group meeting outputs as well: (report) http://tools.ietf.org/html/rfc4984 -Chris
