208 CommPlete Communications Server

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.

To review or configure OSPF areas, press E

NTER to open the List of Areas. To edit an

area in the List of Areas, select it and press E

NTER. To create a new area, press INSERT.

In both cases the Area Configuration window opens with the following options:

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 to be a collection of networks, in actuality an area is

specified to be 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 open the List of Address Ranges window, select an area in the List of Areas

window and press F2. To edit an address range, select it and press E

NTER. To add a

new address range, press I

NSERT. In both cases the Address Range Configuration

window opens with the following options.

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.
