Dual-Homing Protection for MPLS and the MPLS Transport Profile Pseudowires
RFC 8184, “Dual-Homing Protection for MPLS and the MPLS Transport Profile Pseudowires”, is an Informational document published in June 2017 by W. Cheng, L. Wang, H. Li, S. Davari, J. Dong. The canonical text is published by the RFC Editor.
Abstract
This document describes a framework and several scenarios for a pseudowire (PW) dual-homing local protection mechanism that avoids unnecessary switchovers and does not depend on whether a control plane is used. A Dual-Node Interconnection (DNI) PW is used to carry traffic between the dual-homing Provider Edge (PE) nodes when a failure occurs in one of the Attachment Circuits (AC) or PWs. This PW dual-homing local protection mechanism is complementary to existing PW protection mechanisms.
