You do not want to intentionally break anything. My plan is to set up a
separate SSID that has IPv6 only, probably with NAT64 also, this allows
individual users who what to participate to do so.
However, by using a separate SSID, if there is breakage that prevents a
user from doing there job, they can simply change back to the normal
SSID and do their job.
We used a similar strategy when turning-on IPv6 Dual-Stack several years
ago. Over 6 months we had over 5000 people use that separate SSID
without any reported IPv6 related issues, only general wireless issues.
This was used as evidence to management for enabling IPv6 Dual-Stack
on the production wireless SSID and phasing out the separate SSID.
The goal this time wouldn't be to converge the production and separate
IPv6 only SSID anytime soon. But to create an extended voluntary
testing environment. Also, the separate SSID provides an option when
the production SSID runs out of IPv4 addresses.
So, please DO NOT do anything that intentionally breaks an unsuspecting
user, this is a really bad idea and is counter productive to the IPv6
cause. Even this possibly misguided campaign calls for this to be a
voluntary action.
I say possibly misguided, because telling my boss that I can't work
because something doesn't support IPv6 seems to be going a little too
far. Telling my boss that I'm participating in this IPv6 only day and
it my take a little longer while I try something in IPv6 only first then
switching back if it doesn't work, seems much more reasonable to me.
Thanks.
