[6bone] IPv6 routing table size

(Hopefully this is the right list for this question....)

I have been curious about the size of routing tables when using IPv6.  I
had it in my mind that they would be considerably smaller due to
aggregation properties.  I surmised that even a large enterprise may not
have more than a couple hundred routes in their core.  Then I noticed in
a presentation that someone in China (BII Group - presentation from IPv6
Summit in Beijing) was building an IPv6 router with over a million
entries in their routing table.  Am I off track?

Large enterprises today may have tens of thousands of routes in v4, but
using v6 wouldn't they be an order of magnitude smaller?

Thanks,
Jeff
