Abstract

This document describes a simple and efficient mechanism to detect data-plane failures in 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, as well as a mechanism to verify the data plane against the control plane, thereby localizing faults.

    Detecting Multiprotocol Label Switched (MPLS) Data-Plane Failures

Abstract

   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.
