option 212 for 6RD

[Mikael Abrahamsson]

I would like to know other peoples experiences with "just turning on" IPv6 
by means of 6RD via DHCP option 212.

I can see a few potential problems:

* Breakage of some CPEs would somehow misbehave when they see a "new" DHCP 
option.

* Some CPEs behave badly because of their 6RD implementation and customers 
get a worse experience than otherwise.

* Power users with IPv6 tunnels themselves might get upset (they're 
usually a vocal bunch) because they might have to change things to instead 
run the ISP 6RD (which by nature will not be 100% static addresses unless 
they have static IPv4 address).

Any insights and thougts appreciated!
