IBM 8260 manual This is the 32-bit integer identifying the Stub Area, Metric

This parameter is read-only and contains 32-bit unsigned sum of the Link-state-advertisement′s link-state checksum contained in this area′ s link-state database. This sum can be used to determine if there has been a change in a router′s link-state database and to compare the link-state database of two routers.

Note: Area 0.0.0.0, by definition, is the backbone area and is always present in the OSPF area table.

4.When an area border router is connected to a stub area, it generates a default link summary into the area, indicating a default route. You can specify the default routes advertised by the Multiprotocol Interconnect module when acting as an area border router. To do so, you must select OSPF Area Default Metric Table from the OSPF Menu. An example of the resulting panel is shown in Figure 172.

Figure	172. LMS OSPF Area Default Metric Table

This table allows you to specify the following parameters for each entry:

∙

∙

∙

Area ID

This is the 32-bit integer identifying the Stub Area.

TOS

This parameter specifies the Type Of Service associated with the metric.

Metric

This parameter contains the metric value applied at the indicated Type Of Service.

5.You can define a range for an area. Ranges are address/mask pairs that allow you to group subnetted networks that reside in the same area, and to have that group be advertised by one network summary advertisement. Otherwise, a summary advertisement would be generated for each subnet in the area. To define a range for an area, select OSPF Area Address Range
