Internet Engineering Task Force Luca Martini Internet Draft George Swallow Intended status: Standards Track Cisco Expires: April 17, 2011 October 17, 2010 MPLS LSP Status aggregation protocol for Static Pseudowires draft-martini-pwe3-status-aggregation-protocol-00.txt Status of this Memo This Internet-Draft is submitted to IETF in full conformance with the provisions of BCP 78 and BCP 79. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet- Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress."

This Internet-Draft will expire on April 17, 2010 Abstract This document describes a method includes generating an aggregated pseudowire status message on Multi-Protocol Label Switching (MPLS) network Label Switched Path (LSP). The method for transmitting the pseudowire (PW) status information is not new, however these protocol extension allows a Service Provider (SP) to reliably use the PW static status messages on individual PWs. The aggregated pseudowire status message configured to verify a current status of all pseudowires on the LSP.
