The IESG has approved the following document: - 'Pseudowire Redundancy' (draft-ietf-pwe3-redundancy-09.txt) as Informational RFC This document is the product of the Pseudowire Emulation Edge to Edge Working Group. The IESG contact persons are Stewart Bryant and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-pwe3-redundancy/ 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. Working Group Summary This document represents the consensus of the working group. Document Quality There are no concerns regarding the document's quality. Personnel Andy Malis is the Document Shepherd for this document. Stewart Bryant is the Responsible Area Director. 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. END
