Configuring OSPF Interfaces

You should specify a routing interface for any local subnet that needs to communicate with other network segments located on this router or elsewhere in the network. First configure a VLAN for each subnet that will be directly connected to this router, assign IP interfaces to each VLAN (i.e., one primary interface and one or more secondary interfaces), and then use the OSPF / Network Area Address Configuration page to assign an interface address range to an OSPF area.

After assigning a routing interface to an OSPF area, you need to use the OSPF / Interface Configuration page to configure the interface-specific parameters used by OSPF to select the designated router, control the timing of link state advertisements, set the cost used to select preferred paths, and specify the method used to authenticate routing messages.
