Default – Acts as the backbone area (also known as area zero). It forms 
the core of an OSPF network. All other areas are connected to it, and 
inter-area routing occurs via a router connected to the backbone area.

Stub – Does not receive external routes. External routes are defined as 
routes, which are distributed in OSPF via another routing protocol. 
Therefore, the Stub area relies on a default route to send traffic routes 
outside the present domain.

Not-so-stubby – A type of stub area that can import autonomous system 
(AS) external routes and send them to the default/backbone area, but can 
not receive AS external routes from the backbone or other areas.

To define the global OSPF parameters:

1. From the main menu, click Summit Switch Configuration. The Summit 

Switch Configuration screen is displayed.

2. In the left pane, click Routing Protocols. The Routing Protocols screen is 

displayed. 

3. Click the OSPF tab. 

4. From the Port Status drop-down list, click Enabled. The OSPF is enabled on 

the port.

Note: Only the interfaces defined as router type are available for OSPF neighborhood 
establishment.

5. In the Link Cost text box, type the OSPF standard for your network for this 

port.

The Link Cost is the cost of sending a data packet on the interface. The lower 
the cost, the more likely the interface will be used to forward the data traffic.

Note: If more than one port is enabled for OSPF, you must prevent the Summit WM 
Switch from serving as a router for the other traffic. In order to do this, you must set 
the Link Cost to its maximum value of 65535.

6. From the Authentication drop-down list, click the authentication type of 

OSPF on your network: 

None: The default is None. If None is selected, leave the Password text 
box blank.
