[6tisch] review of draft-ietf-6tisch-enrollment-enhanced-beacon

["Pascal Thubert (pthubert)" <[e-mail]>]

Dear all

In preparation of WGLC, please find a review of draft-ietf-6tisch-enrollment-enhanced-beacon-01

Page2 Introduction: there's an EDNOTE: field. It could be useful but not necessary to make the proposed addition. Is the author willing to? Or should a coauthor help?


Page2 section 1.1; please use

1.1.  BCP 14

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in BCP
   14 [RFC2119] [RFC8174] when, and only when, they appear in all
   capitals, as shown here.

Section 1.3

There's a XXX leftover. What is the intention?


"



   proxy priority  the proxy prority value contains a number from 0 to

      0x7f.  Lower numbers are considered to be a higher preference.  A

      priority of 0x7f indicates that the announcer should never be

      considered as a viable enrollment proxy.  Lower value indicates

      willing to act as a Join Proxy as described in

      [I-D.ietf-6tisch-minimal-security<https://tools.ietf.org/html/draft-ietf-6tisch-enrollment-enhanced-beacon-01#ref-I-D.ietf-6tisch-minimal-security>].  Only unenrolled pledges look

      at this value.

"
Maybe indicate first that the field indicates the willingness to act as join proxy? Also, a typo (prority).


P and R bits definition; though it is quite obvious, the description does not say that 'R' is the RA bit and that 'P' is the Proxy Address bit. Maybe use the term flag, like in" the 'P' flag".

   join-proxy lower-64  if the P bit is set, then 64 bits (8 bytes) of

      address are present.  The Link Layer address of the Join Proxy is

      fe80 (as for any Link Layer address), and the bits given in this

      field.

I think you mean Link-Local not link layer? What about:

"


   join-proxy Interface ID  if the P bit is set, then 64 bits (8 bytes) of

   address are present. This field provides the suffix of the Link_Local

   address of the Join Proxy. The associated prefix is well-known as

   fe80::/64.

Do you intend to fill that section?
