The IESG has approved the following document: - 'M-ISIS: Multi Topology (MT) Routing in IS-IS ' <draft-ietf-isis-wg-multi-topology-12.txt> as a Proposed Standard This document is the product of the IS-IS for IP Internets Working Group. The IESG contact persons is Russ Housley. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-isis-wg-multi-topology-12.txt Technical Summary 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. Working Group Summary This document has had several Last Calls in the WG. The WG has consensus on advancing this document. Comments were received during IETF Last Call and the spec was revised accordingly. Protocol Quality Alex Zinin and Bill Fenner reviewed this document for the IESG. There are at least two implementations. RFC-Editor Note: Section 7.1. Multi-Topology TLV, last para: OLD: This MT TLV can advertise up to 127 MTs and it can occur multiple times if needed within IIHs and LSP fragment zero. The result MT NEW: This MT TLV can advertise up to 127 MTs. It is announced in IIHs and LSP fragment 0, and can occur multiple times.
