OSPFv3 Area Index Configuration

Command Syntax and Usage
area <area index> area-id <IP address>
Defines the IP address of the OSPFv3 area number.
Command mode: Router OSPF3
area <area index> type {transit|stub|nssa} {no-summary}
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. External routes from outside the Autonomous System (AS) can be advertised
within the NSSA but are not distributed into other areas.
Enables or disables the no-summary option. When enabled, the area-border router neither
originates nor propagates Inter-Area-Prefix LSAs into stub/NSSA areas. Instead it generates a
default Inter-Area-Prefix LSA.
The default setting is disabled.
Command mode: Router OSPF3
area <area index> default-metric <metric value (1-16777215)>
Configures the cost for the default summary route in a stub area or NSSA.
Command mode: Router OSPF3
area <area index> default-metric type <1-3>
Configures the default metric type applied to the route.
This command applies only to area type of Stub/NSSA.
Command mode: Router OSPF3
