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.
