IS-IS Autoconfiguration
Abstract
This document specifies IS-IS autoconfiguration mechanisms. The key
components are IS-IS System ID self-generation, duplication
detection, and duplication resolution. These mechanisms provide
limited IS-IS functions and are therefore suitable for networks where
plug-and-play configuration is expected.

RFC 8196 IS-IS Autoconfiguration July 2017
1. Introduction
This document specifies mechanisms for IS-IS [RFC1195] [ISO_IEC10589]
[RFC5308] to be autoconfiguring. Such mechanisms could reduce the
management burden for configuring a network, especially where plug-
and-play device configuration is required.
IS-IS autoconfiguration is comprised of the following functions:
