    Authors, WG,
    
    One further comment on this draft.
    
    In the IANA considerations section you request the creation of a new registry for the "ARP/ND Extended Community Flags octet". The registry has a number of unassigned Flags. However, the draft does not specify a registration policy for this registry.
    
    Please can you propose a suitable registration policy. See section 4 of RFC 8126 for information on the different policies. 
    
    Thanks
    
    Matthew

        I am the document shepherd for this draft. Please see below for my comments. Please treat these as you would any other WG last call comments.
        
        Best regards

        General:
        Why do you say the EVPN ARP/ND Extended Community is optional? Don’t you always use it if you comply to the procedures in the draft? Also, I am not clear why in section 3 you say the PE will follow the procedures (which I interpret as a MUST), but there are no MUSTs in e.g. 3a.
        
        Please clarify in the draft.
        
        Please also check the capitalization of RFC2119 keywords throughout. For example, there are a few instances where a 'may' should be a 'MAY'
        
        Abstract and 1. Introduction
        This document proposes an OPTIONAL extended community that is
           advertised ...
        
        Change to 'this document defines an extended community..."
        
        	
        Section 1.1 Terminology and Conventions:
        "Address Resolution Protocol (ARP) Requests or Neighbor Discovery (ND) - or Neighbor Solicitation (NS) - messages are replied locally by the PE,"
        This text seems to mix up Neighbor Discovery (the process) with Neighbor Solicitation (the message). I would suggest deleting Neighbor Discovery from this sentence.
        
        1. Use of the EVPN ARP/ND Extended Community
        
        A PE may learn the IPv6->MAC pair and its associated ND Flags in the management plane or snooping Neighbor Advertisement messages coming from the CE.
        
        s/management plane or snooping Neighbor/management plane or by snooping Neighbor
