existing entry.
Step 4 Enter the IP address of the summary address in the IP Address field. You cannot change this information

Configuring OSPF Interface Parameters
You can alter some interface-specific OSPF parameters as necessary.
Prerequisites
You are not required to alter any of these parameters, but the following interface parameters must be
consistent across all routers in an attached network: the Hello interval, the Dead interval and the
Authentication key. Be sure that if you configure any of these parameters, the configurations for all
routers on your network have compatible values.
To configure OSPF interface parameters, perform the following steps:
In ASDM, the Interface pane lets you configure interface-specific OSPF routing properties, such as
OSPF message authentication and properties. There are two tabs that help you configure interfaces in
OSPF:
•
•
Step 1 In the main ASDM window, choose Configuration > Device Setup > Routing > OSPF > Interface.
Step 2 Click the Authentication tab.
This tab displays the authentication information for the adaptive security appliance interfaces.
Double-clicking a row in the table opens the dialog for the selected interface.
Step 3 Click Edit.
The Edit OSPF Authentication Interface dialog box appears and opens for the selected interface. The
Edit OSPF Interface Authentication dialog box lets you configure the OSPF authentication type and
parameters for the selected interface.
Choose the Authentication type from the Authentication drop-down list. Options include:

Authentication tab—The Authentication tab displays the OSPF authentication information for the
adaptive security appliance interfaces.
Properties tab—The Properties tab displays the OSPF properties defined for each interface in a table
format.
None—Choose this option to disable OSPF authentication.
Authentication Password—Choose this option to use clear text password authentication. This is
not recommended where security is a concern.
MD5—Choose this option to use MD5 authentication (recommended).
Area—(Default) Choose this option to use the authentication type specified for the area (see the
"Configuring OSPF Area Parameters" section on page 21-12
authentication). Area authentication is disabled by default. So, unless you have previously specified
an area authentication type, interfaces set to area authentication have authentication disabled until
you configure area authentication.
