Hello Meral

Many thanks for your review!

For now there is the MoP value for 7 is not defined. When it is, it will signal an extension. So it means future. This draft covers the transition with legacy nodes. A MoP of 7 when defined will not be usable with legacy nodes, there will be a flag day in between.

We want that future to support RFC 8138 so there is no need for transition flag. And we want it always on after that, leaving management control only if that’s wanted.

Additional note: the current mind of the group is that RPLv2 will be indicated by a MoP field set to 7 and the new mode of operation indicated in a new option. If that happens as expected, a value of MoP<7 will mean RPLv1. We could not really cast that in stone in this little draft, it may still change, so we only specify the code behaviour without expanding on that background.

Was that your questions?

Keep safe;

Pascal

I am the assigned Gen-ART reviewer for this draft. The General Area Review Team (Gen-ART) reviews all IETF documents being processed by the IESG for the IETF Chair.  Please treat these comments just like any other last call comments.

Summary: This draft is ready to be published as Standards Track RFC but I have some comments.

Major issues:

Minor issues:

Nits/editorial comments:
-[Page 4] Section 3:
"Section 6.3.1 of [RFC6550] defines a 3-bit Mode of Operation (MOP) in
   the DIO Base Object.  For MOP values 0 to 6, the use of compression
   depends on the "T" flag as specified in this document. A MOP value
   of 7 and above MUST use compression by default and ignore the setting
   of the "T" flag.
"

It was not clear to me at first read why "A MOP value of 7 and above MUST use compression by default and ignore the setting of the "T" flag" ?

Meral
