Configuring OSPF
This section describes how to enable an OSPF process on the ASA.
After you enable OSPF, you need to define a route map. For more information, see the “Defining a Route
Map” section on page 26-4. Then you generate a default route. For more information, see the
“Configuring Static and Default Routes” section on page25-2.
After you have defined a route map for the OSPF process, you can customize the OSPF process to suit
your particular needs, To learn how to customize the OSPF process on the ASA, see the “Customizing
OSPF” section on page 27-4.
To enable OSPF, you need to create an OSPF routing process, specify the range of IP addresses
associated with the routing process, then assign area IDs associated with that range of IP addresses.
You can enable up to two OSPF process instances. Each OSPF process has its own associated areas and
networks.
To enable OSPF, perform the following steps:
Step1 In the main ASDM window, choose Configuration > Device Setup > Routing > OSPF > Setup.
In the OSPF Setup pane, you can enable OSPF processes, configure OSPF areas and networks, and
define OSPF route summarization.
The three tabs in ASDM used to enable OSPF are as follows:
•The Process Instances tab allows you to enable up to two OSPF process instances. After you check
the Enable Each OSPF Process check box, you can enter a unique identifier numeric identifier for
that OSPF process. This process ID is used internally and does not need to match the OSPF process
ID on any other OSPF devices; valid values range from 1 to 65535. Each OSPF process has its own
associated areas and networks.
