I beg to differ, IPv4 is the problem, completely independent of "PI" and "PA" or anything we do with IPv6, by design.

And why do you have gear that got no problem with an exploding IPv4 table after exhaustion, but
can't cope with 20k IPv6 prefixes? I still don't get that. Please, someone finally explain to me
why 20k or even 100k IPv6 Prefixes in the DFZ is a problem, my lab says, even my 5year old Ciscos and Junipers
have no problems with that right now.
The default for an old Sup720 is 500k IPv4 + 250k IPv6 prefixes or so for example (IIRC, was some time ago i tested that).

Are you saying that we should not deploy IPv6?

Guys, really, cope with the reality. Don't be like politicians and create FUD.
