IS-IS in an Interior Gateway Protocol developed in the 1980s by Digital Equipment Corporation (DEC) and submitted to the International Organization for Standardization (IOS) as the routing protocol for Open System Interconnection (OSI). The creation creation of IS-IS was an attempt to produce a standard protocol suite that could allow internetworks to scale.
In recent years, the IS-IS routing protocol has become increasingly popular, with widespread usage among Service Providers. It is a link state protocol, which enables very fast convergence with large scalability. It is also a very flexible protocol and has been extended to incorporate leading edge features such as MPLS Traffic Engineering.
