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 ES-4024A.
Authentication Select an authentication method (Simple or MD5) to activate authentication. Select
None to disable authentication.
Interface(s) and virtual interface(s) must use the same authentication method as the
associated area.
Stub Area 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.
No Summary Select this option to set the ES-4024A to not send/receive LSAs.

default route is added.
