The issue isn't in storing hundreds of thousands, millions,
or tens of millions of routes.  This is, all things considered,
a piece of cake.

The issue is getting the route out of storage, for each packet coming
through the router, at a rate of millions of packets per second for
each core router.  Each IP core router is doing about the same
lookup work as the whole combined PSTN network is for all of its
freely routed numbers.  It is, or should be, quite viable... but not
easy, as we've all found.
