DESCRIPTION
Name
Enter a descriptive name (up to 32 printable ASCII characters) for
identification purposes.
Area ID
Enter a 32-bit ID (that uses the format of an IP address in dotted decimal
notation) that uniquely identifies an area.
A value of 0.0.0.0 indicates that this is a backbone (also known as Area 0).
You can create only one backbone area on the Switch.
Authenticati
on
Select an authentication method (Simple or MD5) to activate
authentication. Select None (default) to disable authentication.
Usually interface(s) and virtual interface(s) should use the same
authentication method as the associated area. If interface(s) and virtual
interface(s) use different authentication methods than the associated area,
the authentication methods are based on the interface(s) and virtual
interface(s) settings.
Stub
Network
Select this option to set the area as a stub area.
If you enter 0.0.0.0 in the Area ID field, the settings in the Stub Area
fields are ignored.

Summary
Select this option to set the Switch to not send/receive LSAs.
Default
Route Cost
Specify a cost (between 0 and 16777214) used to add a default route into
a stub area for routes which are external to an OSPF domain. If you do not
set a route cost, no default route is added.
Add
Click Add to save your changes to the Switch’s run-time memory. The
Switch loses these changes if it is turned off or loses power, so use the
Save link on the top navigation panel to save your changes to the non-
volatile memory when you are done configuring.
Cancel
Click Cancel to begin configuring this screen afresh.
Clear
Click Clear to set the above fields back to the factory defaults.
