Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

To enable Layer 3 routing, assign an IP address to an interface (physical or Loopback). By default, OSPF, similar to all routing protocols, is disabled.

1. Assign an IP address to an interface. CONFIG-INTERFACE mode ip address ip-address mask The format is A.B.C.D/M. If you are using a Loopback interface, refer to Loopback Interfaces .
2. Enable the interface. CONFIG-INTERFACE mode no shutdown
3. Return to CONFIGURATION mode to enable the OSPFv2 process globally. CONFIGURATION mode router ospf process-id The range is from 0 to 65535. The OSPF process ID is the identifying number assigned to the OSPF process. The router ID is the IP address associated with the OSPF process. If you try to enter an OSPF process ID, or if you try to enable more OSPF processes than available Layer 3 interfaces, prior to assigning an IP address to an interface and setting the no shutdown command, the following message displays:

   Dell(conf)#router ospf 1
                                       % Error: No router ID available..
