Usage Information
By default, OSPFv3 graceful restart is disabled and functions only in a helper role to
help restarting neighbor routers in their graceful restarts when it receives a Grace LSA.
When configured in a helper-reject role, an OSPFv3 router ignores the Grace LSAs that
it receives from a restarting OSPFv3 neighbor.
The graceful-restart role command is not supported in OSPFv3. When you enable the
helper-reject role on an interface, you reconfigure an OSPFv3 router to function in a
“restarting-only” role.
