Configuring OSPF Area Parameters

You can optionally configure several OSPF area parameters. These parameters include authentication for
password-based protection against unauthorized access to an area, stub areas, and not-so-stubby-areas
(NSSAs). Stub areas are areas into which information on external routes is not sent. Instead, the area
border router (ABR) generates a default external route into the stub area for destinations outside the
autonomous system (AS). An NSSA does not flood all LSAs from the core into the area, but can import
AS external routes within the area by redistribution.

Purpose
Configure the OSFP network type for the specified interface. Select
one of these network types:
• broadcast—Specify an OSPF broadcast multi-access network.
• non-broadcast—Specify an OSPF NBMA network.
• point-to-multipoint—Specify an OSPF point-to-multipoint
network. If you do not enter another keyword, the interface is
point-to-multipoint for broadcast media.
point-to-multipoint non-broadcast—Specify an OSPF
•
nonbroadcast point-to-multipoint network.
point-to-point—Specify an OSPF point-to-point network.
•
Return to global configuration mode.
(Optional for point-to-multipoint; required for point-to-multipoint
nonbroadcast) Configure an OSPF routing process and enter router
configuration mode.
(Optional for point-to-multipoint; required for point-to-multipoint
nonbroadcast). Specify a configured OSPF neighbor and assign a
cost to the neighbor.
ip-address—Enter the interface IP address of the OSPF
•
neighbor.
cost number—Specify a cost for the neighbor as an integer from
•
1 to 65535.
On point-to-multipoint broadcast networks, specifying a
Note
neighbor is optional, but if you do specify a neighbor, you
must specify a cost for that neighbor.
On point-to-multipoint nonbroadcast neighbors, you must
specify a neighbor, but assigning a cost to the neighbor is
optional. If not specified, neighbors assume the cost of the
interface, based on the ip ospf cost interface configuration
command.
Return to privileged EXEC mode.
Display OSPF-related interface information.
(Optional) Save your entries in the configuration file.
