Conguration Task List for OSPFv2 (OSPF for IPv4)
The following conguration tasks include two mandatory tasks and several optional tasks.
• Enabling OSPFv2 (mandatory)
• Assigning an OSPFv2 Area (mandatory)
• Enable OSPFv2 on Interfaces
• Conguring Stub Areas
• Conguring LSA Throttling Timers
• Enabling Passive Interfaces
• Enabling Fast-Convergence
• Changing OSPFv2 Parameters on Interfaces
• Enabling OSPFv2 Authentication
• Conguring Virtual Links
• Creating Filter Routes
• Redistributing Routes
• Troubleshooting OSPFv2
1. Congure a physical interface. Assign an IP address, physical or Loopback, to the interface to enable Layer 3 routing.
2. Enable OSPF globally. Assign network area and neighbors.
3. Add interfaces or congure other attributes.
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 congure 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.
