Abstract

There is no capability negotiation done for Label DistributionProtocol (LDP) applications that set up Label Switched Paths (LSPs) forIP prefixes or that signal point-to-point (P2P) Pseudowires (PWs) forLayer 2 Virtual Private Networks (L2VPNs). When an LDP session comesup, an LDP speaker may unnecessarily advertise its local state forsuch LDP applications even when the peer session is established forsome other applications like Multipoint LDP (mLDP) or the Inter-ChassisCommunication Protocol (ICCP). This document defines a solution bywhich an LDP speaker announces to its peer its disinterest in suchnon-negotiated applications, thus disabling the unnecessaryadvertisement of corresponding application state, which would haveotherwise been advertised over the established LDP session.
