To Brian W Moore care of Boguslaw Georges Sebek Neil Seitz Boguslaw Georges Sebek Huub Van Helvoort Yoichi Maeda Steve Trowbridge Greg Jones < greg.jones@itu.int> Ghani Abbas Malcom Betts From Loa Andersson Stewart Bryant Danny McPherson George Swallow CC: David Ward Ross Callon Mark Townsley Jari Arkko Scott Bradner For Action Subject: Definition of MPLS Reserved Label 14 Our review of ITU-T Recommendation Y.1372/G.8113 (Y.17tor) and ITU-T Recommendation Y.1373/G.8114 (Y.17tom) indicates that the usage, behavior and semantics of IETF MPLS Reserved Label 14 as defined by RFC 3429 are being modified. For example, Section 10 of Y.1373/G.8114 defines a number of new OAM PDU types with associated functionality expanded upon throughout the document. IETF MPLS Reserved Labels are assigned by IETF Consensus, as defined in RFC 3032, section 6. IETF consensus was achieved for the allocation of MPLS Reserved Label 14 via publication of RFC 3429. Any update to the usage of IETF MPLS Reserved Label 14 requires updating or replacing RFC 3429 with an RFC containing a description of the new functionality. Without such a document, RFC 3429 will become inconsistent in its description of how IETF MPLS Reserved Label 14 is being used, the stated policy for allocation of IETF MPLS Reserved Labels will not have been met and IETF Process will not have been followed. We would also like to again draw attention to RFC 4929, "Change Process for Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) Protocols and Procedures."
