Parameters
default-route-advertise: Used on an NSSA ABR or an ASBR only. With this keyword, an NSSA ABR
redistributes a default route in a Type-7 LSA into the NSSA area. The ABR redistributes a default route
regardless of whether a default route exists in the routing table. With this keyword, an ASBR redistributes
a default route in a Type-7 LSA only when the default route exists in the routing table.
cost cost: Specifies a cost for the default route, in the range of 0 to 16777214. If no cost is specified, the
default cost specified by the default cost command applies.
nssa-only: Limits the default route advertisement to the NSSA area by setting the P-bit of Type-7 LSAs to
0. By default, the P-bit of Type-7 LSAs is set to 1. If the router acts as both an ASBR and an ABR and FULL
state neighbors exist in the backbone area, the P-bit is set to 0.
route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63
characters. When a default route exists in the routing table and the routing policy is matched, the
command redistributes a default route in a Type-7 LSA into the OSPF routing domain. The routing policy
modifies values in the Type-7 LSA.
type type: Specifies a type for the Type-7 LSA: 1 or 2. If no type is specified, the default type specified by
the default type command applies.
no-import-route: Used on an NSSA ABR to control the import-route command to not redistribute routes
into the NSSA area.
no-summary: Used only on an 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. The area is a totally NSSA area.
suppress-fa: Suppresses the forwarding address in the Type-7 LSAs from being placed in the Type-5
LSAs.
translate-always: Always translates Type-7 LSAs to Type-5 LSAs. This keyword takes effect only on an
NSSA ABR.
translate-never: Never translates Type-7 LSAs to Type-5 LSAs. This keyword takes effect only on an NSSA
ABR.
