1176 Configuring OSPF and OSPFv3
Configuring NSF Settings for OSPFv3
Beginning in Privileged EXEC mode, use the following commands to
configure the non-stop forwarding settings for OSPFv3.
Command Purpose
configure Enter global configuration mode.
ipv6 router ospf Enter OSPFv3 configuration mode.
nsf [ietf ] helper strict-lsa-
checking
Require that an OSPFv3 helpful neighbor exit helper
mode whenever a topology change occurs. Use the ietf
keyword to distinguish the IETF standard
implementation of graceful restart from other
implementations.
nsf [ietf ] restart-interval
seconds
Configure the length of the grace period on the restarting
router.
The
seconds keyword is 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)
nsf helper [planned-only] Allow OSPFv3 to act as a helpful neighbor for a restarting
router. Include the planned-only keyword to indicate
that OSPFv3 should only help a restarting router
performing a planned restart.
nsf [ietf] [planned-only] Enable a graceful restart of OSPFv3.
• 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).
