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.  [STANDARDS-TRACK]
