G. Swallow: AUTHOR [+2]
This document is motivated by two broad issues in connection with diagnosing Point-to-Multipoint (P2MP) Label Switched Paths (LSPs). The first is scalability due to the automatic replication of Multiprotocol Label Switching (MPLS) Echo Request messages as they proceed down the tree. The second, which is primarily motivated by LDP-based P2MP and Multipoint-to-Multipoint (MP2MP) LSPs [RFC6388], is the ability to trace a sub-LSP from leaf node to root node.

Proxy MPLS Echo Request
This document defines a means of remotely initiating Multiprotocol Label Switched Protocol (MPLS) Pings on Label Switched Paths. An MPLS Proxy Ping Request is sent to any Label Switching Router along a Label Switched Path. The primary motivations for this facility are first to limit the number of messages and related processing when using LSP Ping in large Point-to-Multipoint LSPs, and second to enable tracing from leaf to leaf (or root).
