Mechanism for Performing Label Switched Path Ping over MPLS Tunnels
RFC 6424, “Mechanism for Performing Label Switched Path Ping over MPLS Tunnels”, is a Proposed Standard document published in November 2011 by N. Bahadur, K. Kompella, G. Swallow. It updates RFC 4379. It has since been updated by RFC 7537. It has been obsoleted by RFC 8029 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
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. [STANDARDS-TRACK]
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.
