RFC 6720: The Generalized TTL Security Mechanism (GTSM) for the Label Distribution Protocol (LDP)

Still current, but amended. Parts of this document are changed or extended by RFC 7552. Read both.

In plain English — editorial summary, not part of the RFC

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. [STANDARDS-TRACK]
