Abstract:

   The Segment Routing (SR) architecture leverages the paradigm of
   source routing.  It can be realized in the Multiprotocol Label
   Switching (MPLS) network without any changes to the data plane.  This
   document describes using Bidirectional Forwarding Detection (BFD) for
   monitoring individual segment lists of candidate paths of an SR
   Policy.  It documents the use of various BFD modes and features such
   as BFD Demand mode, Seamless BFD, and BFD Echo function with the BFD
   Control packet payload in the Segment Routing over MPLS domain.
   Also, this document defines how to use Label Switched Path Ping to
   bootstrap a BFD session, with optional control of selecting a segment
   list in the reverse direction of the BFD session.
