   The Generalized TTL Security Mechanism (GTSM) describes a generalized
   use of a packets Time to Live (TTL) (IPv4) or Hop Limit (IPv6) to
   verify that the packet was sourced by a node on a connected link,
   thereby protecting the router's IP control-plane from CPU utilization
   based attacks.  This technique improves security and is used by many
   protocols.  This document defines the GTSM use for Label Distribution
   Protocol (LDP).

   This specification uses a bit reserved in RFC 5036 and therefore
   updates RFC 5036.
