Command History
Usage Guidelines
The
nsf
command is a router configuration command and affects all interfaces that are covered by the
designated routing process. The switch supports Cisco NSF for OSPF and EIGRP protocols.
When NSF is enabled and a stack master switchover is detected, the NSF-capable routers rebuild routing
information from NSF-aware or NSF-capable neighbors and do not wait for a restart.
Examples
This example shows how to enable OSPF NSF:
Switch(config)#
router ospf 100
Switch(config-router)#
nsf
Use the
show ip ospf
privileged EXEC command to verify that OSPF NSF is enabled.
This example shows how to enable EIGRP NSF:
Switch(config)#
router eigrp 1
Switch(config-router)#
nsf
Use the
show ip protocols
privileged EXEC command to verify that EIGRP NSF is enabled.
enforce global
(Optional) Cancel OSPF NSF restart when non-NSF-aware neighbors are
detected. These keywords are visible only in OSPF router configuration
mode.
