How do the nodes configure their global addresses? I mean are they
using stateless autconf?
Not sure about what's becoming mandatory and what not.
There's a draft on MN-AR interface talking about _both_
stateless and stateful, haven't checked recently though.
If they do, how do you prevent the nodes from configuring
one address
per prefix the get in the RADV?
By putting M bit to 1 in RA thus instructing MN not to derive
an address from the prefix in RA ('M' stands for managed,
instructing to use DHCP instead).
wouldn't some of the nodes end up with multiple addresses from
different prefixes?
Yes, provided stateless autoconf is used.
No. The goal here is strangely different, actually. The goal is not to
advertise all the prefixes in all the RAs - the RA itself will be
tailored per mobile - so, each mobile will only see the prefix that is
being "assigned" to it.
but how do you achieve that? isn't all a single broadcast link (with
multiple subnets? if this is the case all the nodes see all the RADV,
hence all the nodes configure addresses from all prefixes, right?
The other strange thing here is that the mobile may not know that it is
being "assigned" anything - so, it may continue to use stateless
autoconfig, assuming it is a shared prefix.
i am lost now.... are you using something different than stateless
autocnf and than dhcp? a new address conf protocol for specific for
netlmm?

The other point here that may be considered weird is that although the
prefix is being "assigned" so to say, there is no lifetime for it
(unlike DHCP-PD, for e.g.) - so, I'm not sure if these prefixes are
pretty much permanently assigned or if, based on the NETLMM location
registration information, these are somehow removed.
Vidya
breaking the goal of having one node per prefix?
Not sure about the goal of having one node per prefix, where
is it from?
I know about a netlmm goal needing MN not to change its
address (maybe called CoA, not sure), not sure whether this
is in the reqs draft either.
