Summary: The document is ready for publication as a standards track RFC.

Major issues: none

Minor issues: none

Nits/editorial comments:

- The Abstract should not include references. Just delete "[RFC4601]".

- Perhaps this is a matter of personal taste... but Section 3.5.2 is 
devoted to describe the format of the PIM ECMP Redirect message. I think 
this is a section where you should describe the format, but you shouldn't 
write normative statements as for what to do with those fields. For 
example, I am referring to statements like:

       Address of desired upstream
       neighbor where the downstream receiver SHOULD redirect PIM
       Joins

       the receiving
       router of this message MUST use the "Interface ID", instead of
       "Neighbor Address", to identify the new RPF neighbor

       an ECMP
       Redirect message MUST be discarded if the "Interface ID" field...

I think all these sentences including a normative MUST, SHOULD, etc. 
should be written in Sections 3.1. or 3.2 (Procedures). This means that 
the format (current section 3.5) should be moved to a place prior to 3.1 
and 3.2, because the procedures needs to explain what to do with all 
these fields.
