Configuring Multi-Area OSPF Management

Procedure

1. In the NE Explorer, select the NE and choose Communication > IP Protocol Stack Management from the Function Tree.
2. Click the Multi-area OSPF Management tab.
3. Click New. In the New dialog box, set parameters including ID and IP Address.
   NOTE:

   • The new OSPF area ID cannot be the same as an existing area ID or 255.255.255.255.
   • Specify Network Segment for a new OSPF area. This parameter specifies the interfaces for this area and is set to Network IP address/mask, for example, 129.9.0.0/255.255.0.0, which indicates that the OSPF area contains all interfaces in subnets from 129.9.0.0 to 129.9.255.255.
   • When Automatic Route Aggregation is Disable, perform the procedure for configuring manual aggregation routes by referring to 6.

4. Click Apply. A prompt message is displayed, indicating that the OSPF area is created successfully.
5. Optional: To create multiple network segments for an OSPF area, click Add in the Network Segment area.
   NOTE:

   • The range of the new network segment cannot be the same as that of an existing network segment or subnet in the OSPF area.
   • You can create a maximum of four network segments.
   • When you delete an OSPF area, all network segments in the area must be deleted. The configurations of the deleted area, such as network segments, stub types, and authentication modes, will be deleted together with the area. If you recreate the same area, the configurations must be set again.

6. Optional: If Automatic Route Aggregation is Disable, click Add in the Manual Route Aggregation area to create manual aggregation routes.
   NOTE:

   • Network segment configuration for an ABR always fails to include all IP addresses in an OSPF area. Therefore, automatic route aggregation is less effective and less flexible than manual route aggregation in accurately configuring aggregation routes.
   • If Automatic Route Aggregation is enabled for an area, manual aggregation routes in this area will become ineffective, but the route data remains in the database. When Automatic Route Aggregation is disabled for the area, the manual aggregation routes are enabled automatically.
   • When Automatic Route Aggregation is disabled, you can create a maximum of eight manual aggregation routes and delete automatic aggregation routes in the OSPF area. If you want to modify a specified aggregation route, you need to delete this route first, then create a new one.

7. Set the area authentication mode for each new OSPF area as follows:
   1. In the NE Explorer, select the NE and choose Communication > IP Protocol Stack Management from the Function Tree.
   2. Click the OSPF Parameter Settings tab. In the OSPF Authentication Parameter area, set parameters such as Authentication Type and Authentication Password.
