Subject: Questions on draft-leung-mip4-proxy-mode-03.txt

Hi,

I have a couple of questions on this draft.

First question is on how DHCP Proxy (in the MAG) populates the DHCP
Offer. The draft only indicates that the IPv4 address set to the
received HoA (from the Proxy MIP RRP). 
draft-ietf-mip4-gen-ext-04.txt describes mechanism to provide the host
configuration. Should this internet draft be referenced for the purpose
of obtaining host configuration?

KL> Yes, we will reference this draft in the next version.

Second question, on section 9.3: the draft seems to imply that the MN's
default gateway is set the LMA (the Home Agent). 
The LMA/Home Agent might not be in the same subnet as the HoA. Will this
cause a problem with the IP stack which requires the default gateway to
be in the same subnet as the HoA

KL> We will need to clarify that the MN's default gateway is set to the
LMA/HA's IP address on the subnet associated with the HoA.  This is one
of the information that comes from Config Option Exchange Ext.

Thx.

Kent

Regards,
Paula Tjandra.
