Title: M-ISIS: Multi Topology (MT)Routing in IS-IS
State: Active

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