Julien,
I'd like to know more about that.
As far as I can see, certain parts of 4861-ND just DO NOT WORK on non-
transitive networks.
It's really as simple as that.
So you either make 6LoWPANs transitive at huge cost, or you need
something like 6LoWPAN-ND for those parts.
(Or, you simply ignore that they don't work, which you mostly can for
DAD; we didn't want to do that.)
Please reread section 1, paragraph 2 of 4861 for its area of
applicability.
Gruesse, Carsten
PS.: re the charter:
Getting rid of 4861's address resolution by multicast is indeed just
an optimization.
I happen to believe it is a good one. We can (and should!) debate that.
I would have argued to simply get rid of DAD as well, but there is the
issue of counterfeiting.
So we made a limited extension to make DAD work, which it doesn't for
4861-ND on non-transitive.
etc.
