area nssa

cost
Defaults
None.
Mode
Router configuration: G3(su)‐>router(Config‐router)#
Usage
The use of this command is restricted to ABRs attached to stub and NSSA areas.
Example
This example shows how to set the cost value for stub area 10 to 99:
G3(su)->router(Config)#router ospf 1
G3(su)->router(Config-router)#area 10 default-cost 99
area nssa
Use this command to configure an area as a Not So Stubby Area (NSSA). The no form of this
command changes the NSSA back to a plain area.
Syntax
area area-id nssa [default-information-originate]
no area area-id nssa [default-information-originate]
Parameters
area‐id
default‐
information‐
originate
Defaults
If default‐information‐originate is not specified, no default type will be generated.
Mode
Router configuration: G3(su)‐>router(Config‐router)#
Usage
An NSSA allows some external routes represented by external Link State Advertisements (LSAs)
to be imported into it. This is in contrast to a stub area that does not allow any external routes.
External routes that are not imported into an NSSA can be represented by means of a default
route. This configuration is used when an OSPF internetwork is connected to multiple non‐OSPF
routing domains.
