Sorry for the extra message…I forgot one more nit. :-(

The Abstract does mention that this document Updates rfc7153, but the
Introduction doesn’t.  Please add a sentence — the end of the second
paragraph looks appropriate to me.



On October 12, 2021 at 1:23:15 PM, Alvaro Retana (


Hi!  How are you?

Thank you for this draft, and for the patience!

I just read it.  I have just a couple of comments (see inline).  Feel free
to address them with any other that come in from the IETF LC -- which I'm



[Line numbers from idnits.]

69 1.  Introduction

71   [RFC7153] reorganizes the IANA registries for the type values and
72   sub-type values of the BGP Extended Communities attribute.  As a
73   result the IANA maintained registry entitled "BGP Transitive Extended
74   Community Types" includes a range of Type Values (0x80-0x8F) with
75   Experimental Use registration procedure.  Out of this experimental
76   range the types 0x80, 0x81, 0x82 have been assigned via [RFC8955].
77   The primary use for those types and sub-type registries is non
78   experimental.

[minor] s/with Experimental Use registration procedure./reserved for
Experimental Use.

[major] s/assigned via [RFC8955]./used in [RFC5575] and [RFC7674] (both
documents rendered Obsolete by [RFC8955]).

[major] Please add Informative references to rfc5575 and rfc7674.

80   Section 2 of this document requests the registry cleanup to reflect
81   the actual use of those code-points (removing "Experimental Use" from
82   the sub-type registry names) and changes the registration procedure
83   of the types 0x80, 0x81, 0x82 to first come first serve.

[minor] s/first come first serve./use the First Come First Served policy

85 2.  IANA Considerations
86 2.1.  Registry: BGP Transitive Extended Community Types
114   Furthermore IANA is requested to change the registration procedures
115   of this registry of Type Values 0x80 thru 0x82 to First Come First
116   Serve.  The resulting Registration Procedures should read as in
117   Table 2.

[minor] s/First Come First Serve./First Come First Served [RFC8126].

119       +===========+===============================================+
120       | Range     | Registration Procedures                       |
121       +===========+===============================================+
122       | 0x00-0x3f | First Come First Served                       |
123       +-----------+-----------------------------------------------+
124       | 0x80-0x82 | First Come First Served (see [this document]) |
125       +-----------+-----------------------------------------------+
126       | 0x83-0x8f | Reserved for Experimental Use (see [RFC3692]) |
127       +-----------+-----------------------------------------------+
128       | 0x90-0xbf | Standards Action                              |
129       +-----------+-----------------------------------------------+

131         Table 2: Registration Procedures: BGP Transitive Extended
132                              Community Types

[minor] We need an Informative reference to rfc3692.

166 4.  Acknowledgements

168   The author wants to thank Alvaro Retana, who pointed out, that the
169   IANA registry contains misleading entries in this context.
