Customizing OSPFv2
Configuring OSPFv2 Area Parameters
You can configure several OSPF area parameters. These area parameters (shown in the following task
list) include setting authentication, defining stub areas, and assigning specific costs to the default
summary route. Authentication provides password-based protection against unauthorized access to an
area.
Stub areas are areas into which information on external routes is not sent. Instead, there is a default
external route generated by the ABR into the stub area for destinations outside the autonomous system.
To take advantage of the OSPF stub area support, default routing must be used in the stub area. To further
reduce the number of LSAs sent into a stub area, you can use the no-summary keyword of the area stub
command on the ABR to prevent it from sending a summary link advertisement (LSA Type 3) into the
stub area.
To specify OSPFv2 area parameters for your network, perform the following steps:
Detailed Steps
ospf transmit-delay seconds
Example:
hostname(config-interface)# ospf
transmit-delay 5
Sets the estimated number of seconds required to send a link-state
update packet on an OSPF interface. The seconds value ranges
from 1 to 65535 seconds. The default value is 1 second.
In this example, the transmit-delay is 5 seconds.
ospf network point-to-point non-broadcast
Example:
hostname(config-interface)# ospf network
point-to-point non-broadcast
Specifies the interface as a point-to-point, non-broadcast
network.
When you designate an interface as point-to-point and
non-broadcast, you must manually define the OSPF neighbor;
dynamic neighbor discovery is not possible. See the “Defining
Static OSPFv2 Neighbors” section on page 1-16 for more
information. Additionally, you can only define one OSPF
neighbor on that interface.
Command Purpose
Command Purpose
Step 1
router ospf process_id
Example:
hostname(config)# router ospf 2
Creates an OSPF routing process and enters router configuration
mode for the OSPF process that you want to redistribute.
The process_id argument is an internally used identifier for this
routing process and can be any positive integer. This ID does not
have to match the ID on any other device; it is for internal use
only. You can use a maximum of two processes.
Step 2
Do one of the following to configure optional OSPF area parameters:
