Re: [DMM] I-D Action: draft-ietf-dmm-tn-aware-mobility-02.txt

Dear DMM WG,

Some of the recent discussions in DMM and routing areas regarding this
draft have been addressed in 01 and 02 versions.

Feel free to post your comments.  We (John K.)  will go over the updates in
the next IETF meeting.

Have a great day!
