Area Index Configuration Options (continued)
Command Syntax and Usage
area <0‐5> spf­interval <1‐255>
Configures the minimum time interval, in seconds, between two successive
SPF (shortest path first) calculations of the shortest path tree using the
Dijkstra's algorithm.
The default value is 10 seconds.
Command mode: Router OSPF
area <0‐5> stub­metric <1‐65535>
Configures a stub area to send a numeric metric value. All routes received via that
stub area carry the configured metric to potentially influencing routing decisions.
Metric value assigns the priority for choosing the switch for default route.
Command mode: Router OSPF
area <0‐5> type {transit|stub|nssa}
Defines the type of area. For example, when a virtual link has to be established
with the backbone, the area type must be defined as transit.
transit area: allows area summary information to be exchanged

between routing devices. Any area that is not a stub area or NSSA is
considered to be transit area.
stub area: is an area where external routing information is not

distributed. Typically, a stub area is connected to only one other area.
nssa: Not‐So‐Stubby Area (NSSA) is similar to stub area with additional

capabilities. For example, routes originating from within the NSSA can be
propagated to adjacent transit and backbone areas.
Command mode: Router OSPF
no area <0‐5>
Deletes the OSPF area.
Command mode: Router OSPF
show ip ospf area <0‐5>
Displays the current OSPF configuration.
Command mode: All
