The OSPF - Area tab fields are described in the following table.
Id
A 32-bit integer uniquely identifying an area. Area ID 0.0.0.0 is used for the OSPF backbone.
ospfImportASExtern
The area's support for importing AS external link-state advertisements. Could be importExternal (default), importNotExternal, or importNssa (not so stubby area).
SpfRuns
Used to indicate the number of SPF calculations performed by OSPF.
BdrRtrCount
The total number of area border routers reachable within this area. The value, initially zero, is calculated in each SPF Pass.
ospfASBdrRtCount
The total number of Autonomous System border routers reachable within this area. The value, initially zero, is calculated in each SPF Pass.
LSACount
The total number of link-state advertisements in this area's link-state database, excluding AS External LSAs.
LSACksumSum
The 32-bit unsigned sum of the link-state advertisements. This sum excludes external (LS 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.
Summary
The area's support for Summary advertisements in a stub area.
ImportSummary
The area's support for importing Summary advertisements into a stub area. This field should be used only if ospfImportASExtern or importNssa is set to FALSE.
ActiveCount
The number of active interfaces in this area.
