And why wouldn't the Internet work with 600,000 prefixes in the DFZ?
Now all of a sudden for instance Cisco 7600 3CXL isn't enough to old a full table (at around 750k).
Also, IPv6 uses twice the TCAM resources as IPv4...
so, basically what you are saying is that you know that your routers need an upgrade in 5 years and you don't want to pay for an upgrade or you can't figure out a business plan which covers the costs for that? But you are telling small ISPs/NCOs/"hobbyusers"/whatever THEY don't get their business plan right if they don't can afford paying $$$ for PI space or rather would prefer to pay other bills with the money? WTF?! ------ No, the problem that the small ISPs you are speaking about will have to spend that money to swallow such routing table. And it is not $2000, "slightly" more...
