1. Introduction
[RFC8279] introduces and explains Bit Index Explicit Replication
(BIER) architecture and how it supports forwarding of multicast data
packets.
This document lists the OAM requirements for BIER layer of the
multicast domain. The list can further be used to for gap analysis
of available OAM tools to identify possible enhancements of existing
or whether new OAM tools are required to support proactive and on-
demand path monitoring and service validation.
