Yes.

It can be both ways.. You do have to configure a lot of things, and
configuring the link-local address of each of your MAGs from CLI may be
okay.

Back to my comment, the current description is incomplete. In
deployments where the MAG link-local address is pre-configured, I don't
see why the nMAG is going to the LMA.. I know it is described to fetch
HNP, but from handover point of view, it is sufficient that the MN gets
an RA from the "same" router (i.e., from the same link-local address).
Am I missing anything here?
