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 LSP database synchronization
with its neighbors and a mechanism to optimize LSP database
synchronization, while minimizing transient routing disruption when a
router starts.
