Left Pane—OSPF Areas List
The OSPF Areas list assigns a color, for purposes of representation on the topology map, for each OSPF area configured in the network. NONE shows the color assigned to routers with no OSPF area configured.
In Figure 1, routers with OSPF area 0 configured appear on the topology map as red dots. Those with OSPF area 1 appear as green dots. NONE shows the color assigned to routers with no OSPF area configured.
Select or deselect OSPF areas by selecting or clearing the corresponding check boxes. Only selected areas are displayed in the topology map.
Click Check All to select all check boxes; click Clear All to clear all check boxes.
