Technical Summary

   Multi-Protocol Label Switching (MPLS) Label Switched Path (LSP) Ping
   and traceroute mechanisms are commonly used to detect and isolate
   data plane failures in all MPLS LSPs including Pseudowire (PW) LSPs.
   The PW LSP Ping and traceroute elements, however, are not specified
   for IPv6 address usage.

   This document extends the PW LSP Ping and traceroute mechanisms so
   they can be used with IPv6 PWs, and updates RFC 4379.

Working Group Summary

   There is a general agreement in the MPLS WG that some of our 
   protocols need to be extended to meet requirements present in IPv6 
   networks. This is one of such extension to LSP Ping. 

   There is good support for the document in the MPLS WG.

   This document updates RFC 4379 that was developed in the MPLS WG
   and which covers LSPs and pseudowires. Nevertheless, this document
   was specifically drawn to the attention of the PWE3 WG to ensure cross-
