... as long as it isn't something like a Cisco Catalyst 6509 with SUP720 
and doesn't have a PFC3BXL helping out ...

... or if we conveniently don't classify a Catalyst 65xx as a router
because it was primarily intended as a switch, despite how ISP's commonly

A more accurate statement is probably that "any router that can handle
10s of Gbps is likely to be available in a configuration that is not at
all bothered by the current size of the global table, most likely at some
substantial additional cost."
