do you want an entity in the MSP to assign the HA
to the MN?

I must admit I have not a solution in mind for the moment :(


we can come up with some hacks to the HA discovery
mechanism to force the MN to pick a particular HA,
but I would rather avoid it. it would be better if
you tell us what the scenario and which are the
entities involved. then we can design a solution
for the specific scenario.

A MSP wants to assign a specific HA to a specific MN because:
- the HAs are owned by the MSP (the main reason!!! :)
- the MN uses a specific mobility mechanism (e.g. MIPv6, HMIPv6, NEMO, Monami6)
- the operator wants to loadbalance the charge on the different HAs it
owns during the bootstrapping (e.g to avoid DoS attacks)
- the operator offers different types of QoS on the HAs



another option is to use HA Switch mechanism described
in http://www.ietf.org/internet-drafts/draft-ietf-mip6-ha-switch-00.txt

That could be a solution but I must admit I didn't read it recently.

Best regards.

JMC.
