Summary:

This is mostly a well written document, although unfortunately there
are a number of matters that really need to be looked at.

Major issues:

Abstract

   Examples and inspiration for operators to use BGP Large
Communities.

SB> Even if you just copy the Introduction, the Abstract should really
be expanded
SB> to help the reader understand whether or not they want read the
RFC
SB> or if they had read it what it was about.

============

5.  Security Considerations

   Operators should note the recommendations in Section 11 of BGP
   Operations and Security [RFC7454].

SB> You do not address the question of whether there are new
considerations, or considerations
SB> that are of increased importance? Is there is text somewhere
SB> that discusses the integrity and synchronization of the
parameters
SB> and any consequences that arise?

===========

Minor issues:

2.2.  Action Communities

   Action Communities are added as a label to request that a route be
   treated in a particular way within an AS.  The operator of the AS
   defines a routing policy that adjusts path attributes based on the
   community.  For example, the route's propagation characteristics,
the
   LOCAL_PREF (local preference), the next-hop, or the number of
AS_PATH
   prepends to be added when it is received or propagated can be
   changed.

SB> Although these are well known to the target audience, I think you
SB> need some references in the above para.


Nits/editorial comments: 

6.  IANA Considerations

   None.

SB> A little briefer than normal.
