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 additonally describes a mechansim for a router to
   signal its neighbors that it is preparing to initiate a restart while
   maintaining forwarding plane state.  This allows the neighbors to
   maintain their adjacencies until the router has restarted, but also
   allows the neighbors to bring the adjacencies down in the event of
   other topology changes.

   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 5306.
