Abstract

This document describes an extension to the IS-IS protocol to add operational capabilities that allow for ease of management and control over IP prefix distribution within an IS-IS domain. This document enhances the IS-IS protocol by extending the information that an Intermediate System (IS) router can place in Link State Protocol (LSP) Data Units for policy use. This extension will provide operators with a mechanism to control IP prefix distribution throughout multi-level IS-IS domains.
