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