Title : Pseudowire (PW) Redundancy
Author(s) : P. Muley, V. Place
Filename : draft-ietf-pwe3-redundancy-02.txt
Pages : 15
Date : 2009-10-26
This document describes a framework comprised of few scenarios and
associated requirements where PW redundancy is needed. A set of
redundant PWs is configured between PE nodes in SS-PW applications,
or between T-PE nodes in MS-PW applications. In order for the PE/T-PE
nodes to indicate the preferred PW path to forward to one another, a
new status is needed to indicate the preferential forwarding status
of active or standby for each PW in the redundancy set.
