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.

Non-Configurable Data
。 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".
。 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 a change in a router's link state database, and to compare the link-state database of
two routers.
。 Mode - This field tells you whether the area is or is not a stub area. If the area may be a stub area, a 'Create Stub
Area' button will be displayed. If you have configured the area as a stub area a 'Delete Stub Area' button will be
displayed. Otherwise neither button will be displayed.
Command Buttons
。 Create Stub Area - Configure the area as a stub area.
。 Delete Stub Area - Delete the stub area designation. The area will be returned to normal state.
。 Submit - Send the updated configuration to the switch. Configuration changes take effect immediately. These
changes will not be retained across a power cycle unless a save is performed.
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
Import External LSAs - Import and propagate external LSAs
Import No LSAs - Do not import and propagate external LSAs
