Go tell cisco that. IIRC, the first network I dual-stacked, I was kind of
surprised when I found I could not use authentication in OSPFv3, because
OSPFv3 assumes IPv6 will supply the IPSec to do auth...but these routers
didn't support IPSec. They still managed to route IPv6 and support IPv6
customers...so it really was IPv6...just not the full suite of everything
you'd expect from IPv6.
Your observation simply means that users must be informed when buying
IPv6 devices, just as they must with any product. You can buy either
genuine IPv6 or half-baked IPv6 products. When I speak of IPv6, I speak
only of the genuine article.
Does anyone buy "IPv6 devices"?
The biggest hurdle I've seen with IPv6 adoption (i.e. going dual-stack,
with the idea that we'll gradually transition most things / most traffic
from v4 to v6) is the number of end-user network providers that don't
offer v6 at all. My home cable internet provider still doesn't offer
IPv6. When I asked one of their support people about it recently, I was
told not to worry, they have plenty of v4 addresses left, but it was
implied that they do plan to start offering v6 sometime soon. They should
have started rolling out IPv6 to any customers that wanted it years ago,
so that by today, it would be standard for all their installations to be
dual-stack. But here we are, nearly 2016, and they don't have a single
IPv6 customer (AFAIK) yet.
