Conguration Information
The interfaces must be in Layer-3 mode (assigned an IP address) and enabled so that they can send and receive trac. The OSPF process
must know about these interfaces.
To make the OSPF process aware of these interfaces, they must be assigned to OSPF areas.
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.
