NOTE:
•
The term "router" in this chapter refers to both routers and Layer 3 firewalls.
• The IS-IS configuration is available only in the command line interfaces (CLI).

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.
