This draft is a work item of the IS-IS for IP Internets Working Group of the IETF.
Title : M-ISIS: Multi Topology Routing in IS-IS
Author(s) : T. Przygienda et al.
Filename : draft-ietf-isis-wg-multi-topology-00.txt
Pages : 7

This draft describes an optional implementation technique within
IS-IS [ISO90 , Cal90a , Cal90b] used today by many ISPs for
routing within their clouds. IS-IS is an interior gateway routing
protocol developed originally by OSI and used with IP extensions as
IGP. This draft describes how to run within a single ISIS domain a
set of independent IP topologies that we call Multi-Topologies
(MTs), or Multiple views of Topology. This MT extension can be used
for variety of purposes such as an in-band management network
on top' of the original IGP topology, transport multiple
overlapping IP address spaces in the same protocol, force a subset
of an address space to follow a different topology, or finally,
even maintain a restricted number of protocol based VPNs.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
