OSPF Routing
Select enabled to enable OSPF routing on the server.
Router ID
Type the identifier for the OSPF router. It has the same format as an IP address, but
identifies the router independent of its IP Address.
Area Configuration
Use Area Configuration to review or configure OSPF areas. An OSPF area is made
up of internal routers linked to other areas within an autonomous system (AS) by
area border routers.
When you select Area Configuration, the List of Areas menu appears. To edit an
area in the List of Areas, type its serial number and press E
NTER. To create a new
area, Type A and press E
NTER. In both cases, the Area Configuration menu appears
with the following options:
[ 1] Area ID : 000.000.000.000
[ 2] Stub Area : disabled
[ 3] Inject Default Route : disabled
[ 4] Stub Metric : 1
[ESC] to go to previous menu
Area ID. The identification number assigned to the area. It has the same format as an
IP address, but has the function of defining a summarization point for Link State
Advertisements. The default value is 0.0.0.0, the same as the backbone.
Stub Area. Determines whether AS external advertisements will be flooded through
the area. Cannot be enabled for backbone areas.
Inject Default Route. Determines whether a default route is summarized into a stub
area if the OSPF router is connected to multiple areas.
Stub Metric. Shows the cost of the default route summarized into a stub area.
List of Address Ranges
The List of Address Ranges specifies the address ranges in an OSPF area. Although
an area can be loosely defined as a collection of networks, in actuality an area is
specified as a list of address ranges. Each address range is defined as an address and
mask pair. Many separate networks may be contained in a single address range, just
as a subnetted network is composed of many separate subnets.
To access the List of Address Ranges menu, select Area Configuration, type R for
“ranges,” and then press E
NTER. To edit the address ranges in an area, type the area’s
serial number and press
ENTER. Then type A to add a new address range or E to edit
an address range and press E
NTER. In either case, the Address Range Configuration
menu opens with the following options.
[ 1] Address : 000.000.000.000
[ 2] Mask : 000.000.000.000
[ 3] Status : Advertise
[ESC] to go to previous menu
Address. Type the IP address part of the IP address and IP mask pair. The IP address
and IP network mask pair specify the IP addresses contained in the address range.
For example, the class B address range of X.X.X.X with a network mask of 255.255.0.0
includes all IP addresses from X.X.0.0 to X.X.255.255.
Mask. Type the IP mask part of the IP address and IP mask pair.
