Abstract

   The Label Distribution Protocol (LDP) specification defines
   procedures to exchange label bindings over either IPv4, 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.

   The LDP [RFC5036] specification defines procedures and messages for
   exchanging FEC-label bindings over either IPv4 or IPv6 or both (e.g.
   dual-stack) networks.
