Decraene Status: Standards Track Stream: IETF Date: July 2016 Mailbox: pushpasis.ietf@gmail.com, hannes@rtbrick.com, shraddha@juniper.net, stephane.litkowski@orange.com, bruno.decraene@orange.com Pages: 11 Characters: 23344 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-isis-node-admin-tag-11.txt URL: https://www.rfc-editor.org/info/rfc7917 DOI: http://dx.doi.org/10.17487/RFC7917 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. This document is a product of the IS-IS for IP Internets Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
