[ale] IPv6 funny by Ubiquiti

[agcarver+ale at acarver.net (Alex Carver)]

I was trying to read up on Ubiquiti's support of IPv6 so one Google
search took me to a page where 6rd is being set up on their Edge router.

Take a look at the very last example frame at the bottom of the page
(discussing the ASSIGNEDPREFIXHERE value).
