Abstract
This document describes methods for performing LSP ping (specified inRFC 4379) traceroute over MPLS tunnels and for traceroute of stitchedMPLS Label Switched Paths (LSPs). The techniques outlined in RFC4379 are insufficient to perform traceroute Forwarding EquivalencyClass (FEC) validation and path discovery for an LSP that goes overother MPLS tunnels or for a stitched LSP. This document deprecatesthe Downstream Mapping TLV (defined in RFC 4379) in favor of a newTLV that, along with other procedures outlined in this document, canbe used to trace such LSPs.
