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.
