Abstract

Label Switched Path Ping (LSP ping) [RFC4379] is an Operations, Administration, and Maintenance (OAM) mechanism for Multi-Protocol Label Switching (MPLS) Label Switched Paths (LSPs). This document describes extensions to LSP ping so that LSP ping can be used for on-demand monitoring of MPLS Transport Profile (MPLS-TP) LSPs and pseudowires. It also clarifies the procedures to be used for processing the related OAM packets. This document describes how LSP ping can be used for on-demand connectivity verification (Section 3) and route tracing (Section 4) functions required in [RFC5860] and specified in [RFC6371].

Abstract

   Label Switched Path Ping (LSP ping) is an existing and widely    deployed Operations, Administration, and Maintenance (OAM) mechanism    for Multi-Protocol Label Switching (MPLS) Label Switched Paths    (LSPs).  This document describes extensions to LSP ping so that LSP    ping can be used for on-demand connectivity verification of MPLS    Transport Profile (MPLS-TP) LSPs and pseudowires.  This document also    clarifies procedures to be used for processing the related OAM    packets.  Further, it describes procedures for using LSP ping to    perform connectivity verification and route tracing functions in    MPLS-TP networks.  Finally, this document updates RFC 4379 by adding    a new address type and creating an IANA registry.
