routing protocols.
IS-IS Overview
Intermediate System-to-Intermediate System (IS-IS) is a dynamic routing protocol designed by the
International Organization for Standardization (ISO) to operate on the connectionless network protocol
(CLNP).
The IS-IS routing protocol was modified and extended in RFC 1195 by the International Engineer Task
Force (IETF) for application in both TCP/IP and OSI reference models, and the new one is called
Integrated IS-IS or Dual IS-IS.
IS-IS is an Interior Gateway Protocol (IGP) used within an Autonomous System. It adopts the Shortest
Path First (SPF) algorithm for route calculation.
