Authors,
While reviewing this document during AUTH48, please resolve (as necessary) the
following questions, which are also in the XML file.
1) <!-- [rfced] Please note that the title of the document has been
updated as follows:
a) Abbreviations have been expanded per Section 3.6 of RFC 7322 ("RFC
Style Guide"). Please review.
Original:
LISP Distinguished Name Encoding
Current:
Locator/ID Separation Protocol (LISP) Distinguished Name Encoding
b) Please note that we have added an abbreviated title that appears in
the running header of the pdf version. Please review and let us know
if any updates are necessary.
Original:
[nothing]
Current:
LISP Name Encoding
-->
2) <!-- [rfced] Please insert any keywords (beyond those that appear in
the title) for use on https://www.rfc-editor.org/search. -->
3) <!--[rfced] Neither RFC 9300 nor RFC 9301 have "architecture" in their
title. Are these document "nicknames" or concepts? Please
review this citation and sentence and let us know if any updates
are needed.
Original:
The LISP architecture and protocols ([RFC9300], [RFC9301]) introduces
two new numbering spaces,...
-->
4) <!--[rfced] Is RFC 5280 to be read as one of a group of RFCs? Or is
this the only RFC the reader is being pointed to?
Original:
The Distinguished Name field in this document has no relationship to
the similarly named field in the Public-Key Infrastructure using
X.509 (PKIX) specifications [RFC5280].
Perhaps:
The Distinguished Name field in this document has no relationship to
the similarly named field in the Public-Key Infrastructure using
X.509 (PKIX) specifications (e.g., [RFC5280]).
-->
5) <!--[rfced] Please review uses of NULL in this document.
Particularly:
a) Should these be updated to NUL? Please let us know any changes in
Old/New format or feel free to update the edited XML as desired.
b) We see the following similar uses. Should these be made uniform?
NULL Terminated vs.
NULL (0x00) terminated vs.
terminating NULL 0x00 octet vs.
NULL 0 octet vs.
NULL terminated vs.
NULL octet vs.
null octet
c) Further, we would expect NULL Terminated to be hyphenated in
attributive position (before a noun). Please see how (0x00) can fit
into that scheme.
-->
6) <!--[rfced] We had a few questions about the following text:
Original:
When Distinguished Names are encoded for EIDs, the EID Mask-Len length
of the EIDs as they appear in EID-Records for all LISP control
messages [RFC9301] is the length of the string in bits (including the
terminating NULL 0x00 octet).
a) Might it be helpful to move this citation to RFC 9301 to a
previous/first use of LISP control messages (perhaps in the
Introduction)? Or is this citation covering another/more parts of the
sentence here?
b) Is it redundant to say "the EID Mask-Len length of the EIDs"?
-->
7) <!--[rfced] We are having trouble parsing this sentence. What MUST the
lookups carry?
Original:
Distinguished Name EID lookups MUST carry as an EID Mask-Len length
equal to the length of the name string.
-->
8) <!--[rfced] In the following, please clarify the parenthetical. What
is 5 octets? The null octet itself or the null octet plus
"ietf"?
Original:
For example, if the registered EID name is "ietf" with EID Mask-Len
of 40 bits (the length of string "ietf" plus the null octet is 5
octets), and a Map-Request is received for EID name "ietf.lisp" with
an EID Mask-Len of 80 bits, the Map-Server will return EID "ietf"
with length of 40 bits.
-->
9) <!--[rfced] To what does "LISP Distinguished Name specification"
refer? Is a citation necessary here?
Original:
Practical implementations of the LISP Distinguished Name
specification have been running in production networks for some time.
-->
10) <!--[rfced] We had a few questions regarding this text:
Original:
In a practical implementation of
[I-D.ietf-lisp-site-external-connectivity] on LISP deployments,
routers running as Proxy Egress Tunnel Routers (Proxy-ETRs) register
their role with the Mapping System in order to attract traffic
destined for external networks.
a) Is there an update we can make to describe which part/concept of
the cited document is being practically implemented (e.g., the
registration procedures, requirements, etc.).
b) We note some inconsistencies in the abbreviation for "Proxy Egress
Tunnel Routers":
[I-D.ietf-lisp-site-external-connectivity] seems to use pETR
This document uses Proxy-ETR
Past RFCs have used PETR.
Please review and let us know what, if any, updates are necessary.
-->
11) <!--[rfced] What citation should be added to this sentence to point
the reader to the LISP Site External Connectivity document? Is
this draft-ietf-lisp-site-external-connectivity?
Original:
The Distinguished Name in this case serves as a common reference EID
that can be requested (or subscribed as per [RFC9437]) to dynamically
gather this Proxy-ETR list as specified in the LISP Site External
Connectivity document.
-->
12) <!--[rfced] We had a few questions about these similar sentences
appearing in Sections 9.3-9.5:
a) Perhaps we can update to avoid saying a website has had
experience in these sentences?
b) Should the same citation appear in each of the sentences?
Original:
The open source lispers.net NAT-Traversal implementation
[I-D.farinacci-lisp-lispers-net-nat] has had 10 years of deployment
experience using Distinguished Names for documenting xTRs versus Re-
encapsulating Tunnel Router (RTRs) as they appear in a locator-set.
Perhaps:
At the time of writing, the open-source lispers.net NAT-Traversal
implementation [I-D.farinacci-lisp-lispers-net-nat] has deployed
Distinguished Names for documenting xTRs versus Re-encapsulating
Tunnel Routers (RTRs) as they appear in a locator-set for 10 years.
Original:
The open source lispers.net implementation has had 10 years of self-
documenting RLOC names in production and pilot environments.
Perhaps:
At the time of writing, the open-source lispers.net implementation
[I-D.farinacci-lisp-lispers-net-nat] has self-documented RLOC names in
production and pilot environments.
Original:
The open source lispers.net implementation has had 10 years of
deployment experience allowing xTRs to register EIDs as Distinguished
Names.
Perhaps:
At the time of writing, the open-source lispers.net implementation
[I-D.farinacci-lisp-lispers-net-nat] has deployed xTRs that are
allowed to register EIDs as Distinguished Names for 10 years.
-->
13) <!-- [rfced] We had the following questions related to terminology use
throughout the document:
a) Please review the way that the AFI value is referred to throughout
the text (e.g., using an equals sign, spacing around the equals sign,
etc.). We see:
Address Family Identifier (AFI) 17 "Distinguished Names"
AFI 17 "Distinguished Name"
the AFI value 17
An AFI=17 Distinguished Name
an AFI=17 encoded string
AFI 17
See also: AFI = 1
How may we make these consistent throughout?
b) We see variation in the way the term Distinguished Names is
referred to (i.e., capitalization, pluralization, quotation, etc.).
In addition to the examples in a) above, please also see:
LISP Distinguished Names
AFI 17 "Distinguished Name" and (AFI) 17 "Distinguished Names" (sg/pl)
Distinguished Name (DN)
Please consider if this is the name of the value or the concept in
general during your review and send us updates in either Old/New form
or update the edited XML file directly.
c) We see that the abbreviation DN was used nearly at the end of the
document. Might we reduce some of the inconsistencies by moving the
abbreviation to first use (or the first use that is not to the direct
name of the IANA-registered value) and then using DN thereafter?
d) We see variations in the following forms. Should these be made
consistent?
Mapping System vs. mapping system
EID-Record vs. EID record
RLOC-record vs. RLOC record
-->
14) <!-- [rfced] FYI - We have added expansions for the following
abbreviations per Section 3.6 of RFC 7322 ("RFC Style
Guide"). Please review each expansion in the document carefully
to ensure correctness.
LISP - Locator/ID Separation Protocol
LCAF - LISP Canonical Address Format
-->
15) <!-- [rfced] Please review the "Inclusive Language" portion of the
online Style Guide
<https://www.rfc-editor.org/styleguide/part2/#inclusive_language>
and let us know if any changes are needed. Updates of this
nature typically result in more precise language, which is
helpful for readers.
For example, please consider whether the following should be updated:
whitespace
In addition, please consider whether "tradition" should be updated for
clarity. While the NIST website
<https://www.nist.gov/nist-research-library/nist-technical-series-publications-author-instructions#table1>
indicates that this term is potentially biased, it is also ambiguous.
"Tradition" is a subjective term, as it is not the same for everyone.
Original:
...to start with traditional UDP registrations.

Thank you.
