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.
This document is a product of the IS-IS for IP Internets Working Group of the IETF.
This is now a Proposed Standard.
