Ospf - 3Com 5500G-EI Command Reference Manual

OSPF Configuration Commands 205
For all the routers connected to the NSSA area, the command must be used
nssa
to configure the area as the NSSA attribute.
The parameter is used to generate a default type-7
default-route-advertise
LSA. No matter whether there is route 0.0.0.0 in the routing table on an ABR,
type-7 LSA default route will always be generated. Only when there is route
0.0.0.0 in routing table on ASBR, will a type-7 LSA default route be generated.
On ASBR, the parameter disables an external route that is
no-import-route
imported by OSPF with the command from being advertised to the
import-route
NSSA area.
