IS-IS

This article is about a computer network protocol. For topics with similar names, see Isis (disambiguation).

Intermediate System to Intermediate System (IS-IS, also written ISIS) is a link-state interior gateway protocol (IGP) used to exchange routing information within a network. Routers share network topology information so they can find the most efficient paths for data. IS-IS is typically deployed within a single autonomous system and is used in large enterprise and service provider networks.

The IS-IS protocol is defined in ISO/IEC 10589:2002 as an international standard within the Open Systems Interconnection (OSI) reference design.
