13.3 The OSPF 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.

DESCRIPTION
Select the authentication method used in the RIP network. 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 ID for
MD5 authentication. The ID can be between 1 and 255.
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.
Select this check box to advertise routes that were learned from the
indicated Name.
This field displays other sources of routing information that the ZyWALL
can advertise in the RIP network.
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.
