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. 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. 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.
