Configuring OSPF with ABR on SteelHead SD
2. Choose Routing > OSPF.
3. Click Add OSPF Network .
4. Select the site for the new OSPF network.
After you select a site for an OSPF network, the system automatically populates all the remaining
fields based on the default settings. You can simply click
Submit to create a network using the
default settings. You do not have to explicitly configure the settings.

5. Manually fill out the network attributes that you do not want to inherit:
• Site - Select the site where the OSPF network is located. Optionally, leave the site selection blank to
select the first site in the list shown on the Network Designs > Sites page. Use this method to save
time by quickly creating OSPF networks based on the order in which the sites appear in the site list.
Creating another network and leaving the site selection blank again selects the second site in the
list, and so on.
• Name - Specify a network name.
• Default Area Name - Specify a name for the area.
• Default Area ID - Specify the area in which the zone resides. This ID will typically be one of the
already existing areas in the branch. If not, either specify a 32-bit unsigned number from 0 to
4294967295 or an IPv4 address in dotted decimal notation (x.x.x.x). The default setting is the
backbone area ID 0; however, you can change the value to your existing area ID. For small LANs,
area 0 might be all you need, but as a network grows, you will need more than one area connecting
to area 0.
For a routing device to become an OSPF neighbor with another device, both devices must belong
to the same area ID and their passwords and authentication methods must match.
• Inherit Org Defaults - Click On to allow the OSPF network and area to automatically inherit the
settings when an organization’s default network settings are updated. This OSPF network’s settings
will change to match the new values.
