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 congured 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 recongure an OSPFv3 router to function in a “restarting-only” role.
