The IESG has approved the following document: - 'Pseudowire Preferential Forwarding Status Bit' (draft-ietf-pwe3-redundancy-bit-09.txt) as Proposed Standard 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-bit/ Technical Summary This document describes a mechanism for standby status signaling of redundant pseudowires (PWs) between their termination points. A set of redundant PWs is configured between provider edge (PE) nodes in single-segment pseudowire (SS-PW) applications, or between terminating provider edge (T-PE) nodes in multi-segment pseudowire (MS-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 status bit is needed to indicate a preferential forwarding status of Active or Standby for each PW in a redundant set. In addition, a second status bit is defined to allow peer PE nodes to coordinate a switchover operation of the PW. Finally, this document updates the PW operational status textual convention defined in RFC 5542. 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.
