Table 129 Configuration > Network > Routing > OSPF > Add
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 authentication.
Key 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 authentication
ID 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 Zyxel Device 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.
