Abstract
Systems and methods provide in-band telemetry for Segment Routing over Internet Protocol version 6 (SRv6) Traffic Engineering (TE) tunnel segments, such as using One-Way Active Measurement Protocol (OWAMP), Two-Way Active Measurement Protocol (TWAMP), Simple Two-Way Active Measurement Protocol (STAMP), and the like. A method includes receiving a packet in a Segment Routing network supporting Segment Routing over SRv6 for an SRv6-TE tunnel; determining the packet includes a Segment Routing Header (SRH) with an Operations, Administration, and Maintenance (OAM) Flag (O-Flag) enabled; performing measurements based on the packet being an OAM packet and based on the O-Flag being enabled; and storing the measurements in an OAM session database.
