Advertising Node Administrative Tags in IS-IS
RFC 7917, “Advertising Node Administrative Tags in IS-IS”, is a Proposed Standard document published in July 2016 by P. Sarkar, H. Gredler, S. Hegde, S. Litkowski, B. Decraene. The canonical text is published by the RFC Editor.
Abstract
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
