IS-IS Multi-Instance
RFC 6822, “IS-IS Multi-Instance”, is a Proposed Standard document published in December 2012 by S. Previdi, L. Ginsberg, M. Shand, A. Roy, D. Ward. It has been obsoleted by RFC 8202 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document describes a mechanism that allows a single router to share one or more circuits among multiple Intermediate System to Intermediate System (IS-IS) routing protocol instances.
Multiple instances allow the isolation of resources associated with each instance. Routers will form instance-specific adjacencies. Each instance can support multiple topologies. Each topology has a unique Link State Database (LSDB). Each Protocol Data Unit (PDU) will contain a new Type-Length-Value (TLV) identifying the instance and the topology (or topologies) to which the PDU belongs.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
