Technical Summary This documents describes methods for performing lsp-ping traceroute over mpls tunnels. The techniques specified in [RFC4379] outline a traceroute mechanism that includes FEC validation and ECMP path discovery. Those mechanisms are insufficient and do not provide details in case the FEC being traced traverses one or more mpls tunnels and in case where LSP stitching is in use. This document defines enhancements to the downstream-mapping TLV [RFC4379] to make it more extensible and to enable retrieval of detailed information. Using the enhanced TLV format along with the existing definitions of [RFC4379], this document describes procedures by which a traceroute request can correctly traverse mpls tunnels with proper FEC and label validations. Working Group Summary The document has been reviewed by the MPLS working and has been progressed in parallel with draft-ietf-mpls-ldp-p2mp through the working group last call process. Document Quality The document is well reviewed by the MPLS working groups. Personnel Ross Callon is the Document Shepherd for this document. Stewart Bryant is the Responsible Area Director.
