A _million_ ? whoa. I count 245 entries in the global v6 table now, and
I am not aware of any v6 ISP with more than a few dozen thousand

One million subnets, yes; this would be totally unaggregated though.
Should not be more than 50k-80k routes aggregated.

I am not sure I would agree with an order of magnitude smaller, but I
think that a v6 routing table should be smaller than the v4 equivalent.
The biggest (v4) routing table I have seen myself is 200k and change.
