Table 300 Configure NSSA of OSPF
Operation
Configure an area to be the NSSA area
Cancel the configured NSSA
Configure the default cost value of the route
to the NSSA
Restore the default cost value of the route to
the NSSA area
All the routers connected to the NSSA should use the nssa command to configure
the area with the NSSA attribute.
The keyword default-route-advertise is used to generate default type-7 LSAs.
When default-route-advertise is configured, a default type-7 LSA route will be
generated on the ABR, even though no default route 0.0.0.0 is in the routing
table. On an ASBR, however, a default type-7 LSA route can be generated only if
the default route 0.0.0.0 is in the routing table.
Executing the keyword no-import-route on the ASBR will prevent the external
routes that OSPF imported through the import-route command from being
advertised to the NSSA. Generally, if an NSSA router is both ASBR and ABR, this
keyword will be used.
The keyword default-cost is used on the ABR attached to the NSSA. Using this
command, you can configure the default route cost on the ABR to NSSA.
By default, the NSSA is not configured, and the cost of the default route to the
NSSA is 1.
When the switch for adjacency state output is enabled, the OSPF adjacency state
changes will be output to the configuration terminal until the switch for adjacency
state output is disabled.
Perform the following configuration in OSPF view.
