Restart Signaling for IS-IS
RFC 5306, “Restart Signaling for IS-IS”, is a Proposed Standard document published in October 2008 by M. Shand, L. Ginsberg. It obsoletes RFC 3847. It has been obsoleted by RFC 8706 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document describes a mechanism for a restarting router to signal to its neighbors that it is restarting, allowing them to reestablish their adjacencies without cycling through the down state, while still correctly initiating database synchronization.
This document additionally describes a mechanism for a restarting router to determine when it has achieved Link State Protocol Data Unit (LSP) database synchronization with its neighbors and a mechanism to optimize LSP database synchronization, while minimizing transient routing disruption when a router starts. This document obsoletes RFC 3847. [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.
