Hi there

I have done a routing directorate review of this draft.
https://datatracker.ietf.org/doc/draft-ietf-dmm-ondemand-mobility/

The Routing Directorate seeks to review all routing or routing-related drafts
as they pass through IETF last call and IESG review, and sometimes on special
request. The purpose of the review is to provide assistance to the Routing ADs.
For more information about the Routing Directorate, please see
http://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir

Although these comments are primarily for the use of the Routing ADs, it would
be helpful if you could consider them along with any other IETF Last Call
comments that you receive, and strive to resolve them through discussion or by
updating the draft.

Document: draft-ietf-dmm-ondemand-mobility-15

Intended Status: Informational

Comments
-----------

The document was easy to read and absorb.

I found this sentence from the abstract a bit misleading: "This document
describes a solution for taking the application needs into account..."  The
word "solution" made me expect that the document would go into detail about how
an IP stack could request the different sorts of IP address from the network. 
In fact, you are proposing an API.  I would recommend changing to "This
document proposes an API that an application can use to inform the IP stack of
its requirements for session continuity and/or IP address reachability".

On a related point, is there any work you can refer to that provides a
mechanism for implementing this API?

The boilerplate in section 2 is out of date.  Please see RFC 8174 for the
latest boilerplate.

On page 6, I spotted a stray ")" in this sentence:

   It is outside the scope of this specification to define how the host
   requests a specific type of prefix and how the network indicates the
   type of prefix in its advertisement or in its reply to a request).
