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.}, }
