              Advertising Node Administrative Tags in IS-IS


   This document describes an extension to the IS-IS routing protocol to    advertise node administrative tags.  This optional capability allows    tagging and grouping of the nodes in an IS-IS domain.  The node    administrative tags can be used to express and apply locally defined    network policies, thereby providing a very useful operational    capability.  Node administrative tags may be used by either IS-IS    itself or other applications consuming information propagated via IS-    IS.
