               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.
