From: The IESG <firstname.lastname@example.org> To: IETF-Announce <email@example.com> Cc: Internet Architecture Board <firstname.lastname@example.org>, RFC Editor <email@example.com>, isis mailing list <firstname.lastname@example.org>, isis chair <email@example.com> Subject: Protocol Action: 'Restart Signaling for Intermediate System to Intermediate System (IS-IS)' to Proposed Standard The IESG has approved the following document: - 'Restart Signaling for Intermediate System to Intermediate System (IS-IS) ' <draft-ietf-isis-rfc3847bis-01.txt> as a Proposed Standard This document is the product of the IS-IS for IP Internets Working Group. The IESG contact persons are Ross Callon and David Ward. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-isis-rfc3847bis-01.txt
Technical Summary 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 LSP database synchronization with its neighbors and a mechanism to optimize LSP database synchronization, while minimizing transient routing disruption when a router starts. Working Group Summary This is one in a series of seven IS-IS documents that was originally published as informational for historic reasons, that are being updated to proposed standard. There is broad WG consensus for this upgrade. Document Quality There are multiple implementations and some deployment. Personnel Chris Hopps and Dave Ward are jointly acting as shepherds for the series of seven documents. Ross Callon is responsible AD.
