Network Menu: OSPF Areas/Domains
The OSPF Areas/Domains option allows you to view existing area or domain definitions. Depending on the hardware type, this option will appear as either “area” or “domain”. They both have the same options, so for the sake of simplicity in this document, we will refer to “area” only. Keep in mind that it also applies to domains.
Areas are network partitions designed to make the network more scalable. Network summary information is exchanged between two areas through gateways.
When you select Network > Protocols> OSPF Areas, the Areas information window will appear. The first table displays the current area definitions while the second table lists the nodes and links in the currently selected area.
Node Details: When this menu is selected, the Nodes view will appear and display information regarding the nodes in the selected domain/area.
Link Details: When this menu is selected, the Links view window will appear and display information regarding the links in the selected domain/area.
Create Group: This menu will create a group for the nodes in the selected area.
Add: Opens dialog at the top of the window which allows you to add a new domain/area.
Delete: Deletes the selected area in this window.
Link OSPF Settings
To enable OSPF for a link and to specify an area for a link, modify a link from the Links window by selecting Modify > Links. In the Protocols tab, set OSPF to “yes” and select an Area.
