Hi

I have been selected as the Routing Directorate reviewer for this draft. 
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-mpls-seamless-mcast-15
Reviewer: Stig Venaas
Review Date: 2 February 2015
IETF LC End Date: 2 February 2015
Intended Status: Proposed Standard

Summary:
The document is fairly well written. I only found minor editorial
issues, plus potentially a missing IANA action.

The document states in e.g.
6.2.2. Leaf A-D Route for Global Table Multicast
that the RD in the MCAST-VPN NLRI is set to all 1s for (*,G)-state.
Is this use of RD defined in another document? Shouldn't RD type
65535 then be assigned for this purpose in
http://www.iana.org/assignments/route-distinguisher-types/route-distinguisher-types.xhtml

Minor issues:

Section 3:
The reader is suppose to be familiar with MVPN procedures and
               ^^^^^^^^

although this by no means imply that this alternative
                           ^^^^^^

5.1.2. Routes re-avertise by PE or ASBR
               ^^^^^^^^^^^
5.2.2. Routes re-avertise by PE or ASBR
               ^^^^^^^^^^^
