Abstract

   In-situ Operations, Administration, and Maintenance (IOAM) records
   operational and telemetry information in the packet while the packet
   traverses a path between two points in the network.  This document
   presents new flags in the IOAM Trace Option headers.  Specifically,
   the document defines the Loopback, Active, and Immediate Export
   flags.

1.  Introduction

   IOAM [I-D.ietf-ippm-ioam-data] is used for monitoring traffic in the
   network by incorporating IOAM data fields into in-flight data
   packets.

   IOAM data may be represented in one of four possible IOAM options:
   Pre-allocated Trace Option, Incremental Trace Option, Proof of
   Transit (POT) Option, and Edge-to-Edge Option.  This document defines
   three new flags in the Pre-allocated and Incremental Trace options:
   the Loopback, Active, and Immediate Export flags.
