Abstract:
   The Multiprotocol Label Switching (MPLS) Label Switched Path (LSP)
   Ping and Traceroute are used to exercise specific paths of Equal-Cost
   Multipath (ECMP).  When LSP is signaled to use Entropy Label (EL)
   described in RFC6790, the ability for LSP Ping and Traceroute
   operation to discover and exercise ECMP paths has been lost in
   scenarios which LSRs apply deviating load balance techniques.  One
   such scenario is when some LSRs apply EL based load balancing while
   other LSRs apply non-EL based load balancing (ex: IP).  Another
   scenario is when 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 mechanisms to
   restore the ability of exercising specific paths of ECMP over LSP
   which make use of Entropy Label.  This document updates RFC4379,
   RFC6424 and RFC6790.
