Configuring IP Routing
Beginning in privileged EXEC mode, follow these steps to configure area parameters:
Command
Step 1
Router# configure terminal
Step 2
Router(config)#router ospf
process-id
Step 3
Router(config)# area area-id
authentication
Step 4
Router(config)# area area-id
authentication message-digest
Step 5
Router(config)# area area-id stub
[no-summary]
Step 6
Router(config)# area area-id nssa
{no-redistribution|default-informati
on-originate|no-summary}
Step 7
Router(config)# area area-id range
address-mask
Step 8
Router(config)# end
Step 9
Router# show ip ospf [ process-id ]
show ip ospf [ process-id [ area-id ]]
database
Step 10
Router# copy running-config
startup-config
Use the no form of these commands to remove the configured parameter value or to return to the
default value.

Purpose
Enters global configuration mode.
Enables OSPF routing, and enters router configuration
mode.
(Optional) Allows password-based protection against
unauthorized access to the identified area. The identifier
can be either a decimal value or an IP address.
(Optional) Enables MD5 authentication on the area.
(Optional) Defines an area as a stub area. The no-summary
keyword prevents an ABR from sending summary link
advertisements into the stub area.
(Optional) Defines an area as a not-so-stubby-area. Every
router within the same area must agree that the area is
NSSA. Select one of these keywords:
•
no-redistribution—Select when the router is an
NSSA ABR and you want the redistribute command
to import routes into normal areas, but not into the
NSSA.
default-information-originate—Select on an ABR to
•
allow importing type 7 LSAs into the NSSA.
no-redistribution—Select to not send summary LSAs
•
into the NSSA.
(Optional) Specifies an address range for which a single
route is advertised. Use this command only with area
border routers.
Returns to privileged EXEC mode.
Displays information about the OSPF routing process in
general or for a specific process ID to verify configuration.
Displays lists of information related to the OSPF database
for a specific router.
(Optional) Saves your entries in the configuration file.
