   Segment Routing (SR) policy is a set of candidate SR paths consisting
   of one or more segment lists and necessary path attributes.  It
   enables instantiation of an ordered list of segments with a specific
   intent for traffic steering.  In-situ Flow Information Telemetry
   (IFIT) refers to network OAM data plane on-path telemetry techniques,
   in particular the most popular are In-situ OAM (IOAM) and Alternate
   Marking.  This document defines extensions to BGP to distribute SR
   policies carrying IFIT information.  So that IFIT methods can be
   enabled automatically when the SR policy is applied.
