Users Guide

You must configure 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.
Configuration Task List for OSPFv2 (OSPF for
IPv4)
The following configuration tasks include two mandatory tasks and several optional tasks.
• Enabling OSPFv2 (mandatory)
• Assigning an OSPFv2 Area (mandatory)
• Enable OSPFv2 on Interfaces
• Configuring Stub Areas
• Configuring LSA Throttling Timers
• Enabling Passive Interfaces
• Enabling Fast-Convergence
• Changing OSPFv2 Parameters on Interfaces
• Enabling OSPFv2 Authentication
• Configuring Virtual Links
• Creating Filter Routes
• Redistributing Routes
• Troubleshooting OSPFv2
1 Configure 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 configure 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 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.
