992 Configuring OSPF and OSPFv3
nsf [ietf] [planned-only] Enable a graceful restart of OSPF.
• ietf — This keyword is used to distinguish the IETF
standard implementation of graceful restart from other
implementations. Since the IETF implementation is
the only one supported, this keyword is optional.
• planned-only — This keyword indicates that OSPF
should only perform a graceful restart when the restart is
planned (i.e., when the restart is a result of the initiate
failover command).
