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.
