Default command level
2: System level
Parameters
default-route-advertise: Applies only to an NSSA ABR or an ASBR. If it is configured on an NSSA ABR,
the ABR generates a default route in a Type-7 LSA into the NSSA area regardless of whether a default
route is available in the routing table. If it is configured on an ASBR, the ASBR generates a default route
in a Type-7 LSA only when the default route is available in the routing table.
no-import-route: Applies only to an NSSA ABR that is also the ASBR of the OSPF routing domain to
disable redistributing routes in Type-7 LSAs into the NSSA area, making sure that correct external routes
are redistributed.
no-summary: Applies only to an NSSA ABR to advertise a default route in a Type-3 summary LSA into the
NSSA area and to not advertise other summary LSAs into the area. Such an area is a totally NSSA area.
translate-always: Specifies the NSSA ABR as a translator to translate Type-7 LSAs to Type-5 LSAs.
translator-stability-interval value: Specifies the stability interval of the translator, during which the
translator can maintain its translating capability after a device with a higher priority becomes a new
translator. The value argument is the stability interval in the range of 0 to 900 seconds and the default
is 0 (which means the translator does not maintain its translating capability if a new translator arises).
Usage guidelines
All routers attached to an NSSA area must be configured with the nssa command in area view.
