DESCRIPTION
Type the unique, 32-bit identifier for the area in IP address format.
Select the type of area.
Normal - This area is a normal area. It has routing information about
the OSPF AS and about networks outside the OSPF AS.
Stub - This area is an stub area. It has routing information about the
OSPF AS but not about networks outside the OSPF AS. It depends on a
default route to send information outside the OSPF AS.
NSSA - This area is a Not So Stubby Area (NSSA), per RFC 1587. It has
routing information about the OSPF AS and networks that are outside
the OSPF AS and are directly connected to the NSSA. It does not have
information about other networks outside the OSPF AS.
Select the default authentication method used in the area. This
authentication protects the integrity, but not the confidentiality, of
routing updates.
None uses no authentication.
Text uses a plain text password that is sent over the network (not very
secure).
MD5 uses an MD5 password and authentication ID (most secure).
This field is available if the Authentication is Text. Type the password
for text authentication. The key can consist of alphanumeric characters
and the underscore, and it can be up to 8 characters long.
This field is available if the Authentication is MD5. Type the default ID
for MD5 authentication in the area. The ID can be between 1 and 255.
This field is available if the Authentication is MD5. Type the default
password for MD5 authentication in the area. The password can consist
of alphanumeric characters and the underscore, and it can be up to 16
characters long.
This section is displayed if the Type is Normal. Create a virtual link if
you want to connect a different area (that does not have a direct
connection to the backbone) to the backbone. You should set up the
virtual link on the ABR that is connected to the other area and on the
ABR that is connected to the backbone.
This field is a sequential value, and it is not associated with a specific
area.
Type the 32-bit ID (in IP address format) of the other ABR in the virtual
link.
