The IESG has approved the following document: - 'Controlling State Advertisements Of Non-negotiated LDP Applications' (draft-ietf-mpls-ldp-ip-pw-capability-09.txt) as Proposed Standard This document is the product of the Multiprotocol Label Switching Working Group. The IESG contact persons are Adrian Farrel and Alia Atlas. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-mpls-ldp-ip-pw-capability/ Technical Summary There is no capability negotiation done for Label Distribution Protocol (LDP) applications that setup Label Switched Paths (LSPs) for IP prefixes or that signal Point-to-point (P2P) Pseudowires (PWs) for Layer 2 Virtual Private Networks (L2VPNs). When an LDP session comes up, an LDP speaker may unnecessarily advertise its local state for such LDP applications even when the peer session is established for some other applications like Multipoint LDP (mLDP) or Inter-Chassis Communication Protocol (ICCP). This document defines a solution by which an LDP speaker announces to its peer its disinterest in such non-negotiated applications, thus disabling the unnecessary advertisement of corresponding application state, which would have otherwise be advertised over the established LDP session. Working Group Summary There is a strong support for this document in the working group and it has been has been well reviewed. Document Quality We know of ongoing/intended implementations. Personnel Loa Andersson is the document shepherd. Adrian Farrel is the responsible AD.
