Configuration Information
The interfaces must be in Layer-3 mode (assigned an IP address) and enabled so that they can send and
receive traffic. 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 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)
Dell Networking OS supports open shortest path first version 2 (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
• 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.
4 Set the time interval between when the switch receives a topology change and starts a shortest path first
(SPF) calculation.
