The experts of Q10/15 would like to inform you that they have agreed to
consent Recommendation ITU-T G.8113.2/Y.1372.2, “Operations,
Administration and Maintenance mechanism for MPLS-TP networks using the
tools defined for MPLS.”
This Recommendation provides MPLS-TP OAM mechanisms.  It specifies
mechanisms for user-plane OAM (Operations, Administration and
Maintenance) in MPLS-TP networks to meet the MPLS-TP OAM requirements
defined in [IETF RFC 5860]. It also specifies the MPLS-TP OAM packet
formats, syntax and semantics of MPLS-TP OAM packet fields. 
The OAM mechanisms defined in this Recommendation assume common
forwarding of the MPLS-TP user packets and MPLS-TP OAM packets. In
transport networks using co-routed bidirectional point-to-point
connections, the OAM return path is always in band.
Note that the following IDs need to be approved and in the RFC Editor’s
queue by 28 October 2011 in order to initiate the Last Call in the
approval process so that it will complete before the December SG15
1.	draft-ietf-mpls-tp-oam-framework, Operations, Administration and
Maintenance Framework for MPLS-based Transport Networks.
2.	draft-ietf-mpls-tp-cc-cv-rdi, Proactive Connectivity Verification,
Continuity Check and Remote Defect Indication for MPLS-TP.
3.	draft-ietf-mpls-tp-fault, MPLS Fault Management OAM.
4.	draft-ietf-mpls-tp-on-demand-cv, MPLS On-demand Connectivity
Verification and Route Tracing.
The following ID is not required for LC initiation because it is in the
Bibliography section:
5.	draft-ietf-mpls-tp-li-lb, MPLS-TP Lock Instruct and Loopback
