Area ID

Type the unique, 32-bit identifier for the area in IP address format.

Type

This field displays 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.

Authentication

This field displays the default authentication method in the area. Choices are: 

None, Text, and MD5.

Text 

Authentication 

Key

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.

MD5 

Authentication ID

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.

MD5 

Authentication 

Key

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.

Virtual Link

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.

Peer Router ID

Type the 32-bit ID (in IP address format) of the other ABR in the virtual link.

Authentication

Select which authentication method to use in the virtual link. Choices are: None, 

Text, MD5, and Same as Area. In this case, Same as Area refers to the 

Authentication settings above.
