Parameters
default-route-advertise
: Used 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 available in the routing table. If it is configured on an ASBR, the ASBR generates a default route in a
Type-7 LSA only when the default route is available in the routing table.
cost
cost
: Specifies a cost for the default route, in the range of 0 to 16777214. If you do not specify this
option, 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. If you do not specify this keyword, 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 of Type-7 LSAs originated by
the router is set to 0.
