So Philip Smith / Geoff Huston's CIDR report becomes worth a good hard look today

512K routes, here we come.  Lots of TCAM based routers suddenly become
really expensive doorstops.

Maybe time to revisit this old 2007 nanog thread?

Some routing tables hit 512K routes today. Some old hardware and
software can't handle that and either crash or ignore newly learned
routes. So this may cause some disturbances in the force.
