I'm not so sure. I have several customers who are experiencing random
BGP instabilities from time to time. I haven't figured this out
completely yet, but there seems to be a disconnect between the number
of BGP routes and the amount of processing they require (MD5...) and
the CPU speed in the routers.
The entire earth population is not expected to reach 10 billion people
any time soon, which means there cannot possibly be more than 100,000
companies with 100,000 employees world wide, or a million companies
10,000 employees. This pretty much implies that we could flat-route all
the companies with 100,000 employees now, and all of those with 10,000
employees ten years from now...
We can argue whether this is desirable, but a more fundamental
objection is that this implicitly assumes one route per company. In
other words: companies must transport internet traffic between
different sites over their own infrastructure. That's not very cost
effective these days.
