Abstract

   The Label Distribution Protocol (LDP) specification defines
   procedures to exchange label bindings over either IPv4, or IPv6 or
   both networks. This document corrects and clarifies the LDP behavior
   when IPv6 network is used (with or without IPv4). This document
   updates RFC 5036.
