Abstract:

   The MPLS ping and traceroute mechanisms, as described in [RFC8029]
   and the related extensions for Segment Routing (SR) defined in
   [RFC8287], is highly valuable for validating control plane and data
   plane synchronization.  In certain environments, only some
   intermediate or transit nodes may have been upgraded to support these
   validation procedures.  A straightforward MPLS ping and traceroute
   mechanism allows traversing any path without validating the control
   plane state.  [RFC8029] supports this mechanism with the Nil
   Forwarding Equivalence Class (FEC).  The procedures outlined in
   [RFC8029] is primarily applicable when the Nil FEC is used as an
   intermediate FEC in the label stack.  However, challenges arise when
   all labels in the label stack are represented using the Nil FEC.

   This document introduces a new Type-Length-Value (TLV) as an
   extension to the existing Nil FEC.  It describes MPLS ping and
   traceroute procedures using the Nil FEC with this extension to
   address and overcome these challenges.
