Adding a Range to an Area
Ranges are address/mask pairs that let you group subnetted networks residing in
the same area. The router generates a single network summary advertisement for
the group. Without this feature, the router would generate a summary
advertisement for each subnet in the area.
To add a range to an area, begin at the OSPF Area List window shown in Figure
4-15 and complete the following steps:
1. Click on the area for which you want to define a range.
2. Click on Ranges.
The OSPF Range List window opens (Figure 4-16).
3. Click on Add.
The OSPF Range Area window opens (Figure 4-17).
4. Specify the Range Net and Range Mask parameters.
These parameters are described following these instructions.
5. Click on OK.
6. Click on Done to exit the window.
