Areas tab fields

Field	Description
AreaId	The area’s unique identifier. Area ID 0.0.0.0 is
	used for the OSPF backbone.
ImportAsExtern	The area’s support for importing Autonomous
	System external link state advertisements.
	The options available are: importExternal,
	importNoExternal, and importNssa.
SpfRuns	The number of times that the intra-area route
	table has been calculated using this area link
	state database.
AreaBdrRtrCount	The total number of Area Border Routers
	reachable within this area. This is initially zero
	and is calculated in each SPF pass.
AsBdrRtrCount	The total number of Autonomous System
	Border Routers reachable within this area. This
	is initially zero, and is calculated in each SPF
	pass.
AreaLsaCount	The total number of link state advertisements
	in this area’s link state database, excluding
	Autonomous System external link state
	advertisements.
AreaLsaCksumSum	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 into stub areas. It has no effect
	on other areas. If the value is noAreaSummary,
	the router will neither originate nor propagate
	summary link state advertisements into the
	stub area. If the value is sendAreaSummary,
	the router will both summarize and propagate
	summary link state advertisements.
