area-id - Identifies the NSSA. The area ID can be in the form of an
IPv4 address or as a four octet unsigned integer ranging from 0-
4294967295.
translator-role - Indicates NSSA-ABR translator role for Type 5
external LSAs.
candidate - Router translates NSSA LSAs to Type-5 external
LSAs if elected.
never - Router never translates NSSA LSAs to Type-5 external
LSAs.
always - Router always translates NSSA LSAs to Type-5
external LSAs.
no-redistribution - Use this keyword when the router is an NSSA
Area Border Router (ABR) and you want the redistribute command
to import routes only into normal areas, and not into the NSSA. In
other words, this keyword prevents the NSSA ABR from advertising
external routing information (learned via routers in other areas)
into the NSSA.
no-summary - Allows an area to retain standard NSSA features,
but does not inject inter-area routes into this area.
default-information-originate - When the router is an NSSA
Area Border Router (ABR) or an NSSA Autonomous System
Boundary Router (ASBR), this parameter causes it to generate
Type-7 default LSA into the NSSA. This default provides a route to
