no nsf [ietf] helper strict-lsa-checking (OSPFv3)

This command allows OSPF to continue as a helpful neighbor in spite of topology changes.

nsf restart-interval (OSPFv3)

This command configures the length of the grace period on the restarting router. The grace
period must be set long enough to allow the restarting router to reestablish all of its
adjacencies and complete a full database exchange with each of its neighbors.
The ietf parameter is used to distinguish the IETF standard implementation of graceful
restart from other implementations. Since the IETF implementation is not the only one
supported, this parameter is optional. The seconds parameter represents the number of
seconds that the restarting router asks its neighbors to wait before exiting helper mode. The
restarting router includes the restart interval in its grace LSAs (range 1–1800 seconds).
