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.
