Network Working Group S. Yasukawa Request for Comments: 4687 NTT Corporation Category: Informational A. Farrel Old Dog Consulting D. King Aria Networks Ltd. T. Nadeau Cisco Systems, Inc. September 2006 Operations and Management (OAM) Requirements for Point-to-Multipoint MPLS Networks Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Copyright Notice Copyright (C) The Internet Society (2006). Abstract Multi-Protocol Label Switching (MPLS) has been extended to encompass point-to-multipoint (P2MP) Label Switched Paths (LSPs). As with point-to-point MPLS LSPs, the requirement to detect, handle, and diagnose control and data plane defects is critical. For operators deploying services based on P2MP MPLS LSPs, the detection and specification of how to handle those defects are important because such defects not only may affect the fundamentals of an MPLS network, but also may impact service level specification commitments for customers of their network. This document describes requirements for data plane operations and management for P2MP MPLS LSPs. These requirements apply to all forms of P2MP MPLS LSPs, and include P2MP Traffic Engineered (TE) LSPs and multicast LSPs. Yasukawa, et al.

Introduction This document describes requirements for data plane operations and management (OAM) for point-to-multipoint (P2MP) Multi-Protocol Label Switching (MPLS). This document specifies OAM requirements for P2MP MPLS, as well as for applications of P2MP MPLS. These requirements apply to all forms of P2MP MPLS LSPs, and include P2MP Traffic Engineered (TE) LSPs [RFC4461] and [P2MP-RSVP], as well as multicast LDP LSPs [MCAST-LDP]. Note that the requirements for OAM for P2MP MPLS build heavily on the requirements for OAM for point-to-point MPLS. These latter requirements are described in [RFC4377] and are not repeated in this document. For a generic framework for OAM in MPLS networks, refer to [RFC4378]. 2. Terminology 2.1. Conventions Used in This Document The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119].
