Field Description
External Routing A definition of the router's capabilities for the area, including whether or
not AS-external-LSAs are flooded into/throughout the area.
SPF Runs The number of times that the intra-area route table has been calculated
using this area's link-state database. This is done using Dijkstra's
algorithm.
Area Border Router Count The total number of area border routers reachable within this area. This
is initially zero, and is calculated in each SPF Pass.
Area LSA Count The total number of link-state advertisements in this area's link-state
database, excluding AS External LSAs.
Area LSA Checksum The 32-bit unsigned sum of the link-state advertisements' LS
checksums contained in this area's link-state database. 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.
Import Summary LSAs The summary LSAs will be enabled/disabled imported into this area.
