The difference is that the switches and their protocols have been designed from
the beginning for this scale of operation, IP routing protocols are designed for
much fewer endpoints to track.
Anybody who's carrying a full routing table was swallowing on the order
of 528,833 routes (as of Friday's "weekly routing table report" posted
to NANOG). Pretty much everybody and their pet llama accepts full tables
thesedays.
You know anybody who's doing that many entries in an L2 Ethernet broadcast
domain?
The full IP routing tables are something that you normally only have to deal
with in a few devices at the perimeter of your network.
What is being talked about here is routing each /32 IP address individually
throughout your network so that any IP address can be connected anywhere and
have it 'just work' as far as the client on that IP is concerned.
