Abstract:
   Segment Routing (SR) architecture leverages the paradigm of source
   routing.  It can be realized in the Multiprotocol Label Switching
   (MPLS) network without any change to the data plane.  A segment is
   encoded as an MPLS label, and an ordered list of segments is encoded
   as a stack of labels.  Bidirectional Forwarding Detection (BFD) is
   expected to monitor any existing path between systems.  This document
   defines how to use Label Switched Path Ping to bootstrap a BFD
   session, control an SR Policy in the reverse direction of the SR-MPLS
   tunnel, and applicability of BFD Demand mode in the SR-MPLS domain.
   Also, the document describes the use of BFD Echo with BFD Control
   packet payload.
