Geoff Huston, et al provide some useful trending:
With that said, I've been treating hardware forwarding of 1MM v4
prefixes (or equivalent CAM carving of v6, MPLS, ...) as a minimum
requirement for Internet-facing routers with a five-year shelf life.
Platforms claiming in the 500-600k range seem prohibitive just
tracking current v4 prefix growth, and moreso as v6 adaptation
increases and end-users begin to realize that v4 and v6 routing is
fundamentally the same, and begin to de-aggregate/advertise v6 space
just like they do v4...
