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

Document Quality

   There are multiple implementations and some deployment. 


   Chris Hopps and Dave Ward are jointly acting as shepherds for 
   the series of seven documents. Ross Callon is responsible AD.
