Defaults
If default‐information‐originate is not specified, no default type will be generated.
Mode
Router configuration: C2(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.
Example
This example shows how to configure area 10 as an NSSA area:
C2(su)->router(Config)#router ospf 1
C2(su)->router(Config-router)#area 10 nssa default-information-originate

area virtual-link

Use this command to define an OSPF virtual link, which represents a logical connection between
the backbone and a non‐backbone OSPF area. The no form of this command removes the virtual
link and/or its associated settings.
Syntax
area area-id virtual-link router-id
no area area-id virtual-link router-id
In addition to the syntax above, the options for using this command are:
area area-id virtual-link router-id authentication-key key
no area area-id virtual-link router-id authentication-key key
area area-id virtual-link router-id dead-interval seconds
no area area-id virtual-link router-id dead-interval seconds
area area-id virtual-link router-id hello-interval seconds
no area area-id virtual-link router-id hello-interval seconds
area area-id virtual-link router-id retransmit-interval seconds
no area area-id virtual-link router-id retransmit-interval seconds
area area-id virtual-link router-id transmit-delay seconds
no area area-id virtual-link router-id transmit-delay seconds
(Optional) Generates a default of Type 7 into the NSSA. This is used when
the router is an NSSA ABR.
