Cisco nonstop forwarding (NSF) for Open Shortest Path First (OSPF) or Enhanced Interior Gateway
Routing Protocol (EIGRP) routing. Use the no form of this command to disable NSF.

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.
