IS-IS Fast Flooding

Overview

RFC 9681, “IS-IS Fast Flooding”, is an Experimental document published in November 2024 by B. Decraene, L. Ginsberg, T. Li, G. Solignac, M. Karasek, G. Van de Velde, T. Przygienda. The canonical text is published by the RFC Editor.

Abstract

Current Link State PDU flooding rates are much slower than what modern networks can support. The use of IS-IS at larger scale requires faster flooding rates to achieve desired convergence goals. This document discusses the need for faster flooding, the issues around faster flooding, and some example approaches to achieve faster flooding. It also defines protocol extensions relevant to faster flooding.
