Area Table
Process: Select one OSPF Process to display its area list.
Select: Select the desired item for configuration. It is multi-optional.
Area ID: Displays the configured area.
Area Description: Displays the description of the area and it can be modified.
Area Type: Displays the type of the area and it can be modified.
Authentication
Type
：
Displays the authentication type of the area and it can be
modified.
Summary: Displays the Summary parameter and it can be modified.
Redistribution: Displays the Redistribution parameter and it can be modified.
Default Cost: Displays the stub cost of the area and it can be modified.
Default Route
Advertise:
Displays the Default Route Advertise status and it can be
modified.
Metric Type: Displays the type of default route and it can be modified.
Metric: Displays the metric of default route and it can be modified.
SPF runs: Displays the number of times that the intra-
area route table
has been calculated using this area's link-
state database. This
is typically done using Dijkstra's algorithm.
ABR Count: Displays 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: Displays the total number of link-
state advertisements in this
area's link-state database, excluding AS-External LSAs.
Area LSA
Checksum:
Displays 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 l
ink state database,
and to compare the link-state databases of two routers.
10.9.6 Area Aggregation
You can configure address ranges for an area on this page. The address range is used to
consolidate or summarize routes for an area at an area boundary. The result is that a single
summary route is advertised to other areas by the ABR. Routing information is condensed at area
boundaries, a single route is advertised for each address range.
