Abstract

In-situ Operations, Administration, and Maintenance (IOAM) collects operational and telemetry information while the packet traverses a particular network domain. Bit Index Explicit Replication (BIER) is an architecture that provides optimal multicast forwarding through a "multicast domain", without requiring intermediate routers to maintain any per-flow state or to engage in an explicit tree-building protocol. The BIER header contains a bit-string in which each bit represents exactly one egress router to forward the packet to. This document outlines the requirements to carry IOAM data in BIER header and specifies how IOAM data fields are encapsulated in BIER header.
