Mathilde, Julien, All,
The ietf mail server is experiencing some problems and I'm quite sure
which part of the quoted email is written by whom - sorry about that.

Sure it would be nice if that "just worked", but it doesn't.
As far as I see, among the procedures defined in 4861 (address
resolution, NUD, router discovery, prefix discovery, redirect, next hop
determination, parameter discovery, next hop determination, DAD)
ony DAD fails. Just do proxy ND on each lowpan node and this is solved.
Sorry Mathilde but we don't want to do _more_ on each node - these
devices are often times very resource limited and although adding
proxy-nd and full 4861 ND might sometimes be possible it quite often is
not. In the end we would end up having more flavors of 6lowpan, more
options, more cost per device and more _interoperability problems_.
The 6lowpan-nd is currently extremely simplistic, it can be implemented
in a very compact space and thus enables smaller (i.e. more) devices to
be IP enabled.
Best regards,
