Select the IP address for the interface from the IP Address pull-down list.
In the Type field, click the type of OSPF interface you want to create (broadcast, NMBA, or passive).
To designate a router priority, in the RtrPriority field, highlight the current value and type in a new value.
To change their values, highlight the current HelloInterval, RtrDeadInterval, or PollInterval and type in new values for the network.
To enable authentication, in the AuthType field, click either simple Password or MD5.
If you chose simplePassword, in the AuthKey field, type in a password of up to eight characters.
Click Insert.
The OSPF Insert Interfaces dialog box closes.
On the Interfaces tab, click Apply.
The interface is created.
Note:
When an OSPF interface is enabled, you cannot change its interface type. You must first disable the interface, change its type, and then re-enable it. If it is an NMBA interface, you must also first delete its manually-configured neighbors.
