Hi Alice.

I agree that the draft should cover the failure conditions you've
mentioned.  Also, the DHCP relay agent mode will be updated in the
general section.  The specifics of the call flow will be documented in
the WiMAX section and will be aligned accordingly.  This was one of the
comments from WiMAX expert review.  The draft will address the comments
in the next revision.

Kent

Subject: [mip4] Clarify the procedure in the case of DHCP failure or
IPCP failure.

Hello Kent,
                      IMHO, it is required to clarify the procedure in
the case of DHCP failure in section 4.1.1.  Proxy Registration during
Initial Network Attachment.
In step 5,  for some reason, DHCP server may reject such address
assignment or IPCP machine may shut down, the PMIP registration should
be revoked.

Moreover, we should clarify another procedure in which DHCP relay does
not hold DHCP discovery message and forward it to DHCP server before
PMIP registration procedure sepcified in WiMAX.

Best regards
ALice
