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.
