Abstract:
   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 Label Switching
   Routers (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 6790.
