Technical Summary
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 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 redundancy
set.

RFC Editor Note
In the Security Section (5)
Old
This document requires extensions to the Label Distribution Protocol
(LDP) that are needed for protecting pseudowires. These will inherit
at least the same security properties as LDP [RFC5036] and the PW
control protocol [RFC4447].
NEW
The PW redundancy method described in this RFC will require
an extension to the PW control protocol [RFC4447], which in turn is
carried over the Label Distribution Protocol (LDP) [RFC5036].
This PW redundancy method will therefore inherit the
security mechanisms of the version of LDP implemented in
the PEs.
