Abstract

This document describes an optional mechanism within IntermediateSystem to Intermediate Systems (IS-ISs) used todayby many ISPs for IGP routing within their clouds. This documentdescribes how to run, within a single IS-IS domain, a set ofindependent IP topologies that we call Multi-Topologies (MTs).This MT extension can be used for a variety of purposes, such as anin-band management network "on top" of the original IGP topology,maintaining separate IGP routing domains for isolated multicast orIPv6 islands within the backbone, or forcing a subset of an addressspace to follow a different topology.
