Abstract:
   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.
