You must congure OSPF GLOBALLY on the system in CONFIGURATION mode.
OSPF features and functions are assigned to each router using the CONFIG-INTERFACE commands for each interface.
NOTE: By default, OSPF is disabled.
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}]
