This new revision addresses review comments from Acee and Deborah, many
thanks to both of them. No changes were made to the procedures or packet
formats, but a number of text changes were made to improve the language and
overall readability. In addition, some of the sections were rearranged to
improve the flow.

This draft is a work item of the Multiprotocol Label Switching of the IETF.

        Title           : Label Switched Path (LSP) and Pseudowire (PW)
Ping/Trace over MPLS Network using Entropy Labels (EL)

   Multiprotocol Label Switching (MPLS) Label Switched Path (LSP) Ping
   and Traceroute are methods used to test Equal-Cost Multipath (ECMP)
   paths.  Ping is known as a connectivity verification method and
   Traceroute as a fault isolation method, as described in RFC 4379.
   When an LSP is signaled using the Entropy Label (EL) described in RFC
   6790, the ability for LSP Ping and Traceroute operations to discover
   and exercise ECMP paths is lost for scenarios where LSRs apply
   different load balancing techniques.  One such scenario is when some
   LSRs apply EL-based load balancing while other LSRs apply non-EL
   based load balancing (e.g., IP).  Another scenario is when an EL-
   based LSP is stitched with another LSP which can be EL-based or non-
   EL based.

   This document extends the MPLS LSP Ping and Traceroute multipath
   mechanisms in RFC 6424 to allow the ability of exercising LSPs which
   make use of the EL.  This document updates RFC 4379, RFC 6424, and
   RFC 6790.
