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)
Open shortest path rst version 2 (OSPF for IPv4) is supported on the MXL switch.
The following conguration tasks include two mandatory tasks and several optional tasks:
• Enabling OSPFv2 (mandatory)
• Enabling Multi-Process OSPF (OSPFv2 IPv4 Only)
• 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
• 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.
