Abstract

An existing limitation of the protocol defined by [ISO10589] is that only one instance of the protocol can operate on a given circuit. This document defines an extension to IS-IS to remove this restriction. The extension is referred to as "Multi-Instance IS-IS" (MI-IS-IS).

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.

   This document obsoletes RFC 6822.
