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

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

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
