Non-Stop Forwarding

Title Description
nsf
no nsf
Use this command to enable non-stop forwarding. The “no” form of the
command will disable NSF.
Default: Non-stop forwarding is enabled by default.
show nsf Use this command to show the status of non-stop forwarding.
Default: Not applicable
show checkpoint statistics Use this command to display the statistics for the check pointing process.
Default: Not applicable
clear checkpoint statistics Use this command to clear the statistics of the check pointing process.
Default: Not applicable
vlan routing vlanid [index] This command is used to enable routing on a VLAN. Us the “no” form of
the command to disable routing on a VLAN.
Default: Routing is not enabled on any VLANs by default.
nsf [ ietf ] [ planned-only ] Use this command to enable OSPF graceful restart. Use the “no” form of
this command to disable graceful restart.
• 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).
Default: Graceful restart is disabled by default.
nsf helper [ planned-only ] Use this command to allow OSPF to act as a helpful neighbor for a
restarting router. Use the “no” form of this command to prevent OSPF
from acting as a helpful neighbor.
• planned-only — This keyword indicates that OSPF should
only help a restarting router performing a planned restart.
Default: OSPF may act as a helpful neighbor for both planned an
unplanned restarts.
nsf [ietf] helper strict-lsa-checking
no nsf [ietf] helper strict-lsa-checking
This command is used to require that an OSPF helpful neighbor exit
helper mode whenever a topology change occurs. Use the “no” form of
this command to allow OSPF to continue as a helpful neighbor in spite of
topology changes.
Default: A helpful neighbor exits helper mode upon a topology change.
nsf [ietf] restart-interval seconds Use this command to configure the length of the grace period on the
restarting router. Use the “no” form of this command to revert the grace
period to its default.

• 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.

• seconds — 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).
Default: The default restart interval is 120 seconds.
show ip ospf This command has been enhanced to lists the values of the configuration
parameters described above and the status parameters defined in the
RFC 4750 MIB.
