Introduction to Intermediate System to Intermediate System

IS-IS, or Intermediate System to Intermediate System, is an interior gateway protocol used for routing in computer networks. Similar to OSPF (Open Shortest Path First), IS-IS is a link-state routing protocol that facilitates the exchange of routing information. It establishes neighbor adjacencies, defines routing areas, exchanges link-state packets, builds a link-state database, and utilizes the Dijkstra SPF (Shortest Path First) algorithm to determine the optimal path to each destination, which is subsequently installed in the routing table.

In its early days, IS-IS was developed by DEC (Digital Equipment Corporation) for the CLNS (Connectionless-mode Network Service) and CLNP (Connectionless-mode Network Protocol) protocols, both of which were alternatives to IP. Unlike today, where IP is the predominant protocol, IS-IS was originally designed to work with these ISO (International Organization for Standardization) protocols.

The terminology used in IS-IS differs from that of OSPF:

Router in IS-IS is referred to as Intermediate System.

Host is termed as End System.
