Abstract:
In MPLS and 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 PEs
(S-PEs) along the path of the MS-PW. This document describes how to
achieve this protection by updating the existing procedures in RFC
6870. It also contains an optional approach based on MPLS-TP Linear
Protection.
