Configuration with QuickSET

52 QuickSET Configuration Guide

OSPF employs “ﬂooding” to exchange link-states with other routers. Any change in routing

information is ﬂooded to all routers in the network. The use of “areas” puts a boundary on the

explosion of link-state updates. All routers within an area will have the exact link-state database.

Figure 53 OSPF Settings Window

The OSPF Settings window shown in Figure 53 on the previous page, displays a database of areas.

Areas are represented by an address (area ID) similar to an IP address in format; four groups of

three decimal numbers, separated by periods. There is no mask associated with area IDs.

The Import AS External (True or False) ﬁeld, when set to True allows the importation of

Autonomous System external link-state advertisements into the Area ID in the Area ID ﬁeld. To

add an area to the database, click the A

dd Area button.

Use the Add OSPF Area window (shown in Figure 54, below) to add an area to the database. The

Delete Area button will delete the area highlighted in the database in the OSPF Settings Window.
