Abstract
This document describes an optional mechanism within Intermediate
System to Intermediate Systems (IS-ISs) used today by many ISPs for
IGP routing within their clouds. This document describes how to run,
within a single IS-IS domain, a set of independent IP topologies that
we call Multi-Topologies (MTs). This MT extension can be used for a
variety of purposes, such as an in-band management network "on top"
of the original IGP topology, maintaining separate IGP routing
domains for isolated multicast or IPv6 islands within the backbone,
or forcing a subset of an address space to follow a different
topology.
