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]
