MPLS and Ethernet Operations, Administration, and Maintenance (OAM) Interworking

Abstract

This document specifies the mapping of defect states between Ethernet Attachment Circuits (ACs) and associated Ethernet pseudowires (PWs) connected in accordance with the Pseudowire Emulation Edge-to-Edge (PWE3) architecture to realize an end-to-end emulated Ethernet service. It standardizes the behavior of Provider Edges (PEs) with respect to Ethernet PW and AC defects.
