Be careful.
There is text in the draft that talks about ECMP behaviour in different
parts of the path, which implies an expectation that the EL is the sole
source of entropy. If we make this ST then we will be implicitly
standardizing that behaviour. Now as it happens, I thing we need to
update the EL behaviour to make it the sole source of entropy, because
that solves a number of problems, particularly in network
instrumentation, but we need to do that explicitly and not as an
artefact of this draft.
So the way I see it, either this draft is published as informational, or
it is published as ST without any text that implies that the EL is the
sole source of entropy, or we harden the EL behaviour (which I think we
need to do) and this draft is published with a normative reference to an
RFC that specifies the stricter EL behaviour.

Loa,
There’s plenty of RFC 2119 language in the draft, so I support making
this standards track.
Cheers,

Working Group,
February 1st the MPLS working Group requested that draft-ietf-mpls-
spring-entropy-label should be published as an Informational RFC.
During the RTG Directorate and AD reviews the question whether the
document should instead be published as a RFC on the Standards Track
has been raised.
The decision to make the document Informational was taken "a long time
ago", based on discussions between the authors and involving the
document shepherd, on the wg mailing list. At that point it we were
convinced that the document should be progressed as an Informational
document.
It turns out that there has been such changes to the document that we
now would like to request input from the working group if we
should make
the document a Standards Track RFC.
Daniele's RTG Directorate review can be found at at:
https://datatracker.ietf.org/doc/review-ietf-mpls-spring-entropy-label-08-rtgdir-lc-ceccarelli-2018-02-21/
<https://datatracker.ietf.org/doc/review-ietf-mpls-spring-entropy-label-08-rtgdir-lc-ceccarelli-2018-02-21/>
All the issues, with the exception whether it should be Informational
or Standards track, has been resolved as part AD review.
If the document is progressed as a Standard Tracks document then we
also need to answer the question whether this is an update RFC 6790.
This mail starts a one week poll (ending May 9) to see if we have
support to make the document a Standards Track document. If you
support
placing it on the Standards Track also consider if it is an update to
RFC 6790.
Please send your comments to the MPLS wg mailing list (
