Configurable Data
Object
Description
• Import Summary LSAs Select enable or disable from the pulldown menu. If you select enable summary
LSAs will be imported into stub areas.
• Metric Value
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.
• Metric Type
Select the type of metric specified in the Metric Value field.
• OSPF Metric - Regular OSPF metric
• Comparable Cost - External Type 1 metrics that are comparable to the
OSPF metric
• Non-comparable Cost - External Type 2 metrics that are assumed to be
larger than the cost of the OSPF metric
Non-Configurable Data
Object
Description
• Area ID -
The OSPF area. An Area ID is a 32 bit integer in dotted decimal format that
uniquely identifies the area to which a router interface connects.
• Aging Interval -
The Link State Advertisement (LSA) aging timer interval.
• 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. If the area is a stub area,
then these are the possible options for which you may configure the external
routing capability, otherwise the only option is "Import External LSAs".
•
Import External LSAs - Import and propagate external LSAs
•
Import No LSAs - Do not import and propagate external LSAs
• Authentication Type -
Currently set to 'None'.
• SPF Runs -
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.
• 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
