Pseudowire (PW) Operations, Administration, and Maintenance (OAM) Message Mapping

Requirements and Framework for Point-to-Multipoint Pseudowires over MPLS Packet Switched Networks

“…-A solution MUST support OAM message mapping [RFC6310] at the Root PE and Leaf PE if a failure is detected on the source CE.…”

Pseudowire Status for Static Pseudowires

“…If a PE that has received a non-zero status code for a PW detects by any means that the far end PE has become unreachable, it will follow the standard defect entry procedures of [RFC6310], Section 6.2.…”

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

“…Introduction RFC 6310 [RFC6310] specifies the mapping and notification of defect states between a pseudowire (PW) and the Attachment Circuit (AC) of the end-to-end emulated service. It standardizes the behavior of Provider Edges (PEs) with respect to PW and AC defects for a number of technologies (e.g., Asynchronous Transfer Mode (ATM) and Frame Relay (FR)) emulated over PWs in MPLS and MPLS/IP Packet Switched Networks (PSNs).…”

“…It standardizes the behavior of Provider Edges (PEs) with respect to PW and AC defects for a number of technologies (e.g., Asynchronous Transfer Mode (ATM) and Frame Relay (FR)) emulated over PWs in MPLS and MPLS/IP Packet Switched Networks (PSNs). However, [RFC6310] does not describe this function for the Ethernet PW service owing to its unique characteristics.…”

“…This document augments the mapping of defect states between a PW and associated AC of the end-to-end emulated service in [RFC6310]. Similar to [RFC6310], the intent of this document is to standardize the behavior of PEs with respect to failures on Ethernet ACs and PWs, so that there is no ambiguity about the alarms generated and consequent actions undertaken by PEs in response to specific failure conditions.…”
