This document describes a simple and efficient mechanism
that can be
used to detect data plane failures in Multi-Protocol Label
Switching
(MPLS) Label Switched Paths (LSPs).  There are two parts to
this
document: information carried in an MPLS "echo
request" and "echo
reply" for the purposes of fault detection and
isolation, and
mechanisms for reliably sending the echo reply.  [STANDARDS
TRACK]

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

This is now a Proposed Standard Protocol.

standards track
protocol for the Internet community,and requests discussion
and 
suggestions for improvements.Please refer to the current
edition 
of the Internet Official Protocol Standards (STD 1) for the
standardization state and status of this protocol.
