Pseudowire Redundancy
RFC 6718, “Pseudowire Redundancy”, is an Informational document published in August 2012 by P. Muley, M. Aissaoui, M. Bocci. The canonical text is published by the RFC Editor.
Abstract
This document describes a framework comprised of a number of scenarios and associated requirements for pseudowire (PW) redundancy. A set of redundant PWs is configured between provider edge (PE) nodes in single-segment PW applications or between terminating PE (T-PE) nodes in multi-segment PW applications. In order for the PE/T-PE nodes to indicate the preferred PW to use for forwarding PW packets to one another, a new PW status is required to indicate the preferential forwarding status of active or standby for each PW in the redundant set. This document is not an Internet Standards Track specification; it is published for informational purposes.
