Ward Status: Standards Track Stream: IETF Date: December 2012 Mailbox: sprevidi@cisco.com, ginsberg@cisco.com, imc.shand@gmail.com, akr@cisco.com, wardd@cisco.com Pages: 14 Characters: 30254 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-isis-mi-08.txt URL: http://www.rfc-editor.org/rfc/rfc6822.txt 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 is a product of the IS-IS for IP Internets Working Group of the IETF. This is now a Proposed Standard Protocol. STANDARDS TRACK: This document specifies an Internet standards track protocol for the Internet community,and requests discussion and suggestions for improvements. Please refer to the current edition of the Internet Official Protocol Standards (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
