Parameters
default-route-advertise
: Usable on an NSSA ABR or an ASBR only. 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 configured. If it is configured on an ASBR, only a default route is configured on the
ASBR can it generates the default route in a Type-7 LSA into the attached area.
no-import-route
: Usable only on 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
: Usable only on 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 seconds, which is in the range of 0 to 900
and defaults to 0 (which means the translator does not maintain its translating capability if a new
translator arises).
