This draft is not about MPLS, it is about documenting IPv6 use cases.  More explicitly, it is about the case where operators don’t want to use the MPLS control plane with segment routing.

Stewart (in his GenArt review) correctly pointed at the fact that the document used the perceived lack of ability to run MPLS on an IPv6-only network as part of the justification for IPv6-based segment routing.  I think that the correct way to address that is to take the focus away from MPLS – there’s no need to even mention it in use cases that won’t use it.

The authors have agreed to refocus the document that way.

In summary, I don’t think it is necessary for the mpls WG to consider this document.  Even though we already finished IETF LC, it will still take me several weeks before the IESG considers approval (because I’m forwarding this document in a cluster with other related ones), so you can still send comments about it.  However, please wait for the authors to refocus the text and at least post -11 before looking at it.

Thanks!

Alvaro.
