Network Working Group S. Yasukawa Request for Comments: 4687 Ntt Corporation Category: Informational A. Farrel Old Dog Consulting 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. 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. Informational [Page 1] RFC 4687
