In some scenarios, MPLS Transport Profile (MPLS-TP) pseudowires (PWs)
(RFC 5921) may be statically configured when a dynamic control plane
is not available.  A fast protection mechanism for MPLS-TP PWs is
needed to protect against the failure of an Attachment Circuit (AC),
the failure of a Provider Edge (PE), or a failure in the Packet
Switched Network (PSN).  The framework and typical scenarios of dual-
homing PW local protection are described in RFC 8184.  This document
proposes a dual-homing coordination mechanism for MPLS-TP PWs that is
used for state exchange and switchover coordination between the dual-
homing PEs for dual-homing PW local protection.

This document is a product of the Pseudowire And LDP-enabled Services Working Group of the IETF.

This is now a Proposed Standard.
