RE: Open issues list? [Re: New (-02) version of IPv6 CPE Router draft is available for review]

During the presentation at IETF, it was clearly said, the picture is one
addressing scheme.  One may use some other addressing scheme as well.
However, the bullets in that slide do reflect current CPE Router
addressing plan.

Forget RFC4241 for a moment - any router has a loopback interface.  What
one configures on the Loopback interface is left to the user.

The RFC4241 in his section 2.8. Connectivity Monitoring say:
"The old document of APNIC IPv6 address assignment policy required that
APNIC could ping the subnet anycast address to check address usage."

But the APNIC ipv6-policy-280599 is obsolete and the actual policy
(http://www.apnic.net/policy/ipv6-address-policy.html) dont have such
"check address usage".

So, the RFC4241 cannot be used as argument in favour of a loopback
interface.
