[mpls] Fw: I-D Action: draft-smack-mpls-rfc4379bis-02.txt

Hi all,
I have a comment regarding draft-smack-mpls-rfc4379bis-02.

According to the draft, its purpose is "take LSP Ping to an Internet  Standard". As part of this work the authors address all the outstanding Errata to the original RFC 4379, and update the references.

I fully agree with the goal that the authors have set to themselves.

However, I have noticed that there is quite a long list of RFCs  that update RFC 4379, and it would be nice to understand whether these updates have been incorporated or not.

Specifically:
1.  RFC 6424 states that it "deprecates the Downstream Mapping TLV in favor of a new TLV". 
2. RFC 6426 extends applicability of LSP Ping to MPLS-TP thus introducing new  address types and new TLVs
3. RFC 6289  extends LSP Ping to PWs signaled with LDP sessions running on top of IPv6 and introduces new sub-TLVs
4. RFC  7506 clarifies the use of IPv6 Router Alert option for LSP Ping.
5. RFC  7537 has introduced new IANA  registries for various aspects of LSP Ping.

Neither of these RFCs is mentioned anywhere in draft-smack-mpls-rfc4379bis-02.  

Does this mean that if/when the draft is published as an RFC, all the  documents  updating RFC 4379 would equally update a new RFC?

And what would happen to all the TLVs, sub-TLVs and procedures that are defined in these documents?

I honestly do not know what is the right way to proceed here, but I think that silence is definitely not the best way to address the problem.

My 2c,
Sasha

Abstract:
   This document describes a simple and efficient mechanism that can be
   used to detect data plane failures in Multi-Protocol Label Switching
   (MPLS) Label Switched Paths (LSPs).  There are two parts to this
   document: information carried in an MPLS "echo request" and "echo
   reply" for the purposes of fault detection and isolation, and
   mechanisms for reliably sending the echo reply.

   This document obsoletes RFC 4379.
