LABEL

DESCRIPTION

Area ID

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

 

 

Type

Select the type of OSPF 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

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).

 

 

Text Authentication

This field is available if the Authentication is Text. Type the password for text

Key

authentication. The key can consist of alphanumeric characters and the underscore,

 

and it can be up to 16 characters long.

 

 

MD5 Authentication

This field is available if the Authentication is MD5. Type the default ID for MD5

ID

authentication in the area. The ID can be between 1 and 255.

 

 

MD5 Authentication

This field is available if the Authentication is MD5. Type the default password for MD5

Key

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.

 

 

Add

Click this to create a new virtual link.

 

 

Edit

Double-click an entry or select it and click Edit to open a screen where you can modify

 

the entry’s settings.

 

 

Remove

To remove an entry, select it and click Remove. The ZyWALL confirms you want to

 

remove it before doing so.

 

 

#

This field is a sequential value, and it is not associated with a specific area.

 

 

Peer Router ID

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

 

 

Authentication

This is the authentication method the virtual link uses. 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). Hover

 

your cursor over this label to display the password.

 

MD5 uses an MD5 password and authentication ID (most secure). Hover your cursor

 

over this label to display the authentication ID and key.

 

Same as Area has the virtual link also use the Authentication settings above.

 

 

OK

Click OK to save your changes back to the ZyWALL.
