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.
