1.  Introduction

   [I-D.ietf-spring-segment-routing] introduces and explains Segment
   Routing architecture that leverages source routing and tunneling
   standards which can be applied directly to MPLS dataplane with no
   changes on forwarding plane and on IPv6 dataplane with new Routing
   Extension Header.

   This document list the OAM requirements for Segment Routing based
   network which can further be used to produce OAM tools, either
   through enhancing existing OAM tools or constructing new OAM tools,
   for path liveliness and service validation.

2.  Requirements notation

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

3.  Terminology

   SR OAM Packet: OAM probe originated and processed within SR domain(s)

   ECMP: Equal Cost Multipath

   SR: Segment Routing
