In MPLS and MPLS Transport Profile (MPLS-TP) environments, statically
provisioned Single-Segment Pseudowires (SS-PWs) are protected against
tunnel failure via MPLS-level and MPLS-TP-level tunnel protection.
With statically provisioned Multi-Segment Pseudowires (MS-PWs), each
segment of the MS-PW is likewise protected from tunnel failures via
MPLS-level and MPLS-TP-level tunnel protection.  However, static
MS-PWs are not protected end-to-end against failure of one of the
Switching Provider Edge Routers (S-PEs) along the path of the
MS-PW.  This document describes how to achieve this protection via
redundant MS-PWs by updating the existing procedures in RFC 6870.
It also contains an optional approach based on MPLS-TP Linear
Protection.

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

This is now a Proposed Standard.
