The following table describes the labels in this screen.  

OSPF (Open Shortest Path First, RFC 2328) is a link-state protocol designed to distribute 
routing information within a group of networks, called an Autonomous System (AS). OSPF 
offers some advantages over vector-space routing protocols like RIP.

• OSPF supports variable-length subnet masks, which can be set up to use available IP 

addresses more efficiently.

Authentication

Authentication

Select the authentication method used in the RIP network. 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 ID for MD5 
authentication. The ID can be between 1 and 255.

MD5 
Authentication 
Key

This field is available if the Authentication is MD5. Type the password for MD5 
authentication. The password can consist of alphanumeric characters and the 
underscore, and it can be up to 16 characters long.

Redistribute

Active

Select this check box to advertise routes that were learned from the indicated 
Name.

Name

This field displays other sources of routing information that the ZyWALL can 
advertise in the RIP network.

Metric

Type the cost for routes provided by the indicated source. The metric represents 
the “cost” of transmission for routing purposes. RIP routing uses hop count as the 
measurement of cost, with 1 usually used for directly connected networks. The 
number does not have to be precise, but it must be between 0 and 16. In practice, 
2 or 3 is usually used.
