For a complete list of the OSPF commands, refer to the OSPF section in the Dell Networking OS
Command Line Reference Guide document.
Enabling OSPFv2
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.
You must configure at least one interface for Layer 3 before enabling OSPFv2 globally.
If implementing multi-process OSPF, create an equal number of Layer 3 enabled interfaces and OSPF
process IDs. For example, if you create four OSPFv2 process IDs, you must have four interfaces with Layer
3 enabled.
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 [vrf {vrf name}]
• vrf name: enter the keyword VRF and the instance name to tie the OSPF instance to the VRF. All
network commands under this OSPF instance are later tied to the VRF instance.
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.
After the OSPF process and the VRF are tied together, the OSPF process ID cannot be used again in
the system.
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.
