Configuring the OSPF Routing Protocol (Layer 3)

Configuring the OSPF Global Configuration

To globally configure OSPF:

1.In the OSPF Configuration section of the Web Agent window, click Global Configuration. The OSPF Global Configuration dialog box opens.

2.Use Table 9-1 to configure your global setup:
