Stub Area Configuration
To display the Stub Area Configuration page, click Routing OSPFv3 Advanced Stub
Area Configuration.
To configure an OSPFv3 stub area:
1. Use Area ID to enter the OSPF area ID. An Area ID is a 32 bit integer in dotted decimal
format that uniquely identifies the area to which a router interface connects.
2. Use Import Summary LSAs to select enable or disable. If you select enable, summary
LSAs will be imported into areas. Defaults to Enable.
3. Use Default Cost to enter the metric value you want applied for the default route advertised
into the stub area. Valid values range from 1 to 16,777,215. This value is applicable only to
Stub areas.
4. Click ADD to configure the area as a stub area.
5. Click DELETE to delete the stub area designation. The area will be returned to normal state.
Field Description
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.
Type of Service This field is the normal TOS associated with the stub metric.
