Item Description
Syntax originate-default-route [type-7]
no originate-default-route
Context configure>service>vprn>ospf>area>nssa
Description This command enables the generation of a default route and its LSA type (3 or 7) into a Not
So Stubby Area (NSSA) by an NSSA Area Border Router (ABR)
When configuring an NSSA with no summaries, the ABR will inject a type 3 LSA default route
into the NSSA area. Some older implementations expect a type 7 LSA default route.
The no form of the command disables origination of a default route.
Default no originate-default-route — A default route is not originated.
Parameters type-7 — Specifies a type 7 LSA should be used for the default route.
Configure this parameter to inject a type-7 LSA default route instead the type 3 LSA into the
NSSA configured with no summaries.
To revert to a type 3 LSA, enter originate-default-route without the type-7 parameter.
Default: Type 3 LSA for the default route.
Item Description
Syntax [no] redistribute-external
Context configure>service>vprn>ospf>area>nssa
Description This command enables the redistribution of external routes into the Not So Stubby Area
(NSSA) or an NSSA area border router (ABR) that is exporting the routes into non-NSSA
areas.
NSSA or Not So Stubby Areas are similar to stub areas in that no external routes are imported
into the area from other OSPF areas. The major difference between a stub area and an NSSA
is that the NSSA has the capability to flood external routes that it learns (providing it is an
ASBR) throughout its area and via an Area Border Router to the entire OSPF domain.
The no form of the command disables the default behavior to automatically redistribute
external routes into the NSSA area from the NSSA ABR.
Default redistribute-external — External routes are redistributed into the NSSA.
