Left Pane—ISIS Areas List
The ISIS Areas list assigns a color, for purposes of representation on the topology map, for each IS-IS area identifier configured in the network. The area identifier is the first three bytes of the ISO network entity title (NET) address. In Figure 1, routers whose NET addresses include area identifier 11.0007 appear on the topology map as red dots. Those with area identifier 49.0011 appear as green dots. NONE shows the color assigned to routers with no NET address configured.
ISIS area identifiers can be selected or deselected by selecting or clearing the corresponding check boxes. Only selected area identifiers are displayed in the topology map.
