Area The unique 32-bit identifiers of areas in the AS, in dotted
decimal notation. Area ID 0.0.0.0 references the backbone
of the AS and cannot be changed or deleted.
Type The types of areas in the AS:
• If an area is a normal OSPF area, “Regular” is displayed.
• If an area is not so stubby, “NSSA” is displayed.
• If an area is a stub, “Stub” is displayed.
For more information, see “Defining OSPF areas” on
page 199.
Authentication The methods for authenticating OSPF packets sent and
received through all FortiGate interfaces linked to each
area:
• When authentication is disabled, “None” is displayed.
• When text-based password authentication is enabled,
“Text” is displayed.
• When MD5 authentication is enabled, “MD5” is
displayed.
A different authentication setting may apply to some of the
interfaces in an area, as displayed under Interfaces. For
example, if an area employs simple passwords for
authentication, you can configure a different password for
one or more of the networks in that area.
Networks The networks in the OSPF AS and their area IDs. When you add a network
to the Networks list, all FortiGate interfaces that are part of the network are
advertised in OSPF link-state advertisements. You can enable OSPF on all
FortiGate interfaces whose IP addresses match the OSPF network address
space.
Create New Select to add a network to the AS, specify its area ID, and
add the definition to the Networks list. See “Specifying
OSPF networks” on page 200.
Network The IP addresses and network masks of networks in the AS
on which OSPF runs. The FortiGate unit may have physical
or VLAN interfaces connected to the network.
Area The area IDs that have been assigned to the OSPF network
address space.
Interfaces Any additional settings needed to adjust OSPF operation on a FortiGate
interface.
Create New Select to add additional/different OSPF operating
parameters for a FortiGate interface and add the
configuration to the Interfaces list. See “Selecting operating
parameters for an OSPF interface” on page 201.
Name The names of OSPF interface definitions.
Interface The names of FortiGate physical or VLAN interfaces having
OSPF settings that differ from the default values assigned to
all other interfaces in the same area.
IP The IP addresses of the OSPF-enabled interfaces having
additional/different settings.
Authentication The methods for authenticating LSA exchanges sent and
received on specific OSPF-enabled interfaces. These
settings override the area Authentication settings.
