This document specifies a mechanism to signal Pseudowire (PW) status messages using a PW associated channel (ACh). Such a mechanism is suitable for use where no PW dynamic control plane exits@ known as static PWs@ or where a Terminating Provider Edge (T-PE) needs to send a PW status message directly to a far-end T-PE. The mechanism allows PW Operations@ Administration@ and Maintenance (OAM) message mapping and PW redundancy to operate on static PWs. This document also updates RFC 5885 in the case when Bi-directional Forwarding Detection (BFD) is used to convey PW status-signaling information.
