RFC 6424: Mechanism for Performing Label Switched Path Ping (LSP Ping) over MPLS Tunnels
This RFC has been replaced. Do not implement against it for new work — it was formally obsoleted by RFC 8029.
Current document in this lineage: RFC 8029 — Detecting Multiprotocol Label Switched (MPLS) Data-Plane Failures
In plain English — editorial summary, not part of the RFC
This document describes methods for performing LSP ping (specified in RFC 4379) traceroute over MPLS tunnels and for traceroute of stitched MPLS Label Switched Paths (LSPs). The techniques outlined in RFC 4379 are insufficient to perform traceroute Forwarding Equivalency Class (FEC) validation and path discovery for an LSP that goes over other MPLS tunnels or for a stitched LSP. This document deprecates the Downstream Mapping TLV (defined in RFC 4379) in favor of a new TLV that, along with other procedures outlined in this document, can be used to trace such LSPs.
