area nssa
This command configures an area as a Not So Stubby Area (NSSA) which 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. It is used when an OSPF
inter‐network is connected to multiple non‐OSPF routing domains.
