Summary of OSPF Configuration Tasks

This section provides a summary of OSPF configuration tasks. Perform configurations according to your particular requirements.

Table 1 describes OSPF configuration tasks.

**Table 1** OSPF configuration tasks
Scenario	Description	Task
Configuring Basic OSPF Functions	Basic OSPF functions must be configured before other OSPF functions can be implemented.	Configuring Basic OSPF Functions Configuring Session Parameters for OSPF Neighbor or Adjacency Relationships Configuring OSPF Attributes on Different Types of Networks
Configuring OSPF Areas	In a stub area, an area border router (ABR) does not transmit autonomous system (AS) external routes, reducing route entries on the ABR as well as the amount of routing information to be transmitted. An NSSA is a special type of OSPF area. Similar to a stub area, an NSSA does not transmit external routes from other areas. Different from a stub area, an NSSA imports AS external routes and transmits them in the entire AS (a stub area does not import AS external routes).	Configuring OSPF Stub Areas Configuring an OSPF NSSA
Adjusting OSPF Route Selection	To implement flexible application of OSPF on the live network, you can adjust OSPF parameters to control OSPF routing.	Adjusting OSPF Route Selection
Controlling OSPF Routing Information	To implement network requirements, you can configure OSPF parameters to control advertisement and receipt of OSPF routes.	Controlling OSPF Routing Information
Controlling the Convergence Speed of OSPF Routes	You can increase the convergence speed of OSPF routes to enable OSPF to quickly respond to changes in the network topology, or reduce the convergence speed to decrease the impact caused by route flapping over OSPF networks and relieve loads on devices.	Configuring OSPF Fast Convergence
Improving Reliability of an OSPF Network	If you configure BFD for OSPF in a process or on an interface, the link status can be rapidly detected. This allows fault detection to complete in milliseconds, speeding up OSPF convergence. To avoid traffic interruption and route flapping caused by standby/active switchovers, you can configure OSPF GR.	Configuring BFD for OSPF Configuring OSPF GR
Improving Stability of an OSPF Network	You can improve the stability of an OSPF network to reduce route flapping on the network. This enables the devices to work in a normal state for an extended period of time.	Improving Stability of an OSPF Network
Improving the Security of an OSPF Network	In an OSPF network demanding high security, you can configure OSPF authentication and GTSM to improve the network security.	Improving the Security of an OSPF Network
