                 GRE Encapsulation for In-situ OAM Data
                      draft-weis-ippm-ioam-gre-00

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
   outlines how IOAM data fields are encapsulated in GRE.
