This may be getting a bit to fuzzy. I'd prefer something more along
the lines of the original statement. Assuming the intention is to
ensure that each IPv6 interface in the CE router can be configured
with a /64, should the requirement not be that the CE router does not
request (or hint for) a prefix that is too small? (without going into
saying how large it actually should be)
Maybe this has been discussed before, but what is the desired
behaviour of the CE router in case the delegated prefix actually is
too small to assign a /64 to each of its interfaces?
