Abstract:
The Generalized TTL Security Mechanism (GTSM) describes a generalized
use of a packet's 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 the Label
Distribution Protocol (LDP).
This specification uses a bit reserved in RFC 5036 and therefore
updates RFC 5036.
