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]
