area virtual-link
Enterasys C3 Configuration Guide 27-15
Parameters
Defaults
If default-information-originate is not specified, no default type will be generated.
Mode
Router configuration: C3(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:
C3(su)->router(Config)#router ospf 1
C3(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.
