Proxy MPLS Echo Request
RFC 7555, “Proxy MPLS Echo Request”, is a Proposed Standard document published in June 2015 by G. Swallow, V. Lim, S. Aldrin. The canonical text is published by the RFC Editor.
Abstract
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).
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
