Intermediate System to Intermediate System Extensions for Advertising Router Information
RFC 4971, “Intermediate System to Intermediate System Extensions for Advertising Router Information”, is a Proposed Standard document published in July 2007 by JP. Vasseur, N. Shen, R. Aggarwal. It has been obsoleted by RFC 7981 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document defines a new optional Intermediate System to Intermediate System (IS-IS) TLV named CAPABILITY, formed of multiple sub-TLVs, which allows a router to announce its capabilities within an IS-IS level or the entire routing domain. [STANDARDS-TRACK]
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.
