              Advertising Node Administrative Tags in OSPF

Abstract

   This document describes an extension to the OSPF protocol to add an
   optional operational capability that allows tagging and grouping of
   the nodes in an OSPF domain.  This allows simplification, ease of
   management and control over route and path selection based on
   configured policies.  This document describes an extension to the
   OSPF protocol to advertise node administrative tags.  The node tags
   can be used to express and apply locally defined network policies,
   which are a very useful operational capability.  Node tags may be
   used by either OSPF itself or other applications consuming
   information propagated via OSPF.

   This document describes the protocol extensions to disseminate node
   administrative tags to the OSPFv2 and OSPFv3 protocol.  It provides
   example use cases of administrative node tags.
