25.5 Configuring OSPF Interfaces
To configure an OSPF interface, first create an IP routing domain in the IP Setup screen (see
Section 7.6 on page 75 for more information). Once you create an IP routing domain, an OSPF
interface entry is automatically created. See Section 25.1 on page 175 for more information on
OSPF.
In the OSPF Configuration screen, click Interface to display the OSPF Interface screen.
