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]
