This document describes a simple and efficient mechanism to detect
data-plane failures in Multiprotocol Label Switching (MPLS) Label
Switched Paths (LSPs).  It defines a probe message called an "MPLS                       
echo request" and a response message called an "MPLS echo reply" for
returning the result of the probe.  The MPLS echo request is intended
to contain sufficient information to check correct operation of the
data plane and to verify the data plane against the control plane,
thereby localizing faults.

This document obsoletes RFCs 4379, 6424, 6829, and 7537, and updates
RFC 1122.

This document is a product of the Multiprotocol Label Switching Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
