Variable Value
import-summaries enable Configures the area support for importing summary
advertisements into a stub area. Use this entry only for
a stub area. To configure this option to the default
value, use the default operator with the command.
The default value is true.
translator-role <value> Indicates an NSSA Border router ability to perform
translation of type-7 LSAs into type-5 LSAs.
Valid values are 1 (always) or 2 (candidate). Default
value is 1 (always).
type <nssa|stub> Configures the type of area. An NSSA prevents
flooding of normal route advertisements into the area
by replacing them with a default route. A stub area
uses only one exit point (router interface) from the
area.
By default, the area is neither a stub area or an NSSA.
Configuring OSPF area ranges
Configure an area address range on the OSPF router to reduce the number of ABR
advertisements into other OSPF areas. An area address range is an implied contiguous range
of area network addresses for which the ABR advertises a single summary route.
Configure the area by using one of the two LSA types: inter-area-prefix-link or nssa-extlink.
You can use any value for the OSPF area name (for example, 1.1.1.1 or 200.200.200.200).
Prerequisites
You must log on to the OSPF Router Configuration mode in the ACLI.
Procedure steps
Configure an OSPF area range by using the following command:
