        Title:      Controlling State Advertisements of Non-negotiated

There is no capability negotiation done for Label Distribution
Protocol (LDP) applications that set up 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 the 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 been advertised over the established LDP session.

This document is a product of the Multiprotocol Label Switching Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
