Dear Sri


Thank you for updating the Proxy-MIP6 draft. We reviewed and discussed
the draft in detail and these are our comments.

First, the draft is written nicely, organized very well; enjoyed
reading it; we thank the authors for the good work.


We did not like the timestamp format change; it was not needed, we
have to make changes to our code.; but fine.

In MAG signaling, you should add the RS and RA flow related points;
You should add a small section  with couple of lines on what the MAG
does when RA arrives; this is missing; it is there in the seq diagram.

Lot of new error checking rules; but good; very detailed

You should specify when the HA should consider the timestamp from MAG
as as outof sync. Suggest some time window  like 1 second; define a
protocol variable. Or, make NTP use a must. Not an issue for us; we
have RO.

On PBU and PBA retransmissions or timeouts, please say it is as per
rfc3775; or define new protocol constants

PBA cannot have the type-II routing header, can it ? there is no home
address ; you should mention this; to avoid interop problems.


Hope this review helps. Thank you again for completing this document; good job.
