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

LABEL DESCRIPTION
Authentication
Authentication 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).
Text
Authentication

Active OSPF Select this to use RIP to advertise routes that were learned through
OSPF.
Metric Type the cost for routes provided by OSPF. 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.
Active Static
Route
Select this to use RIP to advertise routes that were learned through
the static route configuration.
Metric Type the cost for routes provided by the static route configuration.
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.
