The following table describes the Areas tab fields.
Field | Description |
---|---|
AreaId | Specifies the unique identifier for the area. Area ID 0.0.0.0 is used for the OSPF backbone. |
ImportAsExtern | Specifies the area type by defining its support for importing Autonomous System external link state advertisements. The options
available are:
|
SpfRuns | Specifies the number of times that the OSPF intra-area route table has been calculated using this area link state database. |
AreaBdrRtrCount | Specifies the total number of Area Border Routers reachable within this area. This is initially zero and is calculated in each SPF pass. |
AsBdrRtrCount | Specifies the total number of Autonomous System Border Routers reachable within this area. This is initially zero, and is calculated in each SPF pass. |
AreaLsaCount | Specifies the total number of link state advertisements in this area’s link state database, excluding Autonomous System external link state advertisements. |
AreaLsaCksumSum | Specifies the sum of the link state advertisements’ checksums contained in this area’s link state database. This sum excludes external (link state type 5) link state advertisements. The 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. |
AreaSummary | Controls the import of summary link state advertisements on an ABR into a stub area. It has no effect on other areas. If the value is noAreaSummary, the ABR neither originates nor propagates summary link state advertisements into the stub area (creating a totally stubby area). If the value is sendAreaSummary, the ABR both summarizes and propagates summary link state advertisements. |
