Think deployed hardware, lots of it. (Most instances of TCAM share it for IPv4 + IPv6, with each slot on IPv6 taking two slots of TCAM, IIRC. And a few other things also consume TCAM, maybe not as significantly.) (Newer boxes may handle more on some network's cores, but I don't believe it is ubiquitously the case across the DFZ.)
ok, that's fair... but in ~5yrs time we'll work ourslves out of the 1M mark, right? to 5M or 10M? (or something more than 1M)
