The following table describes the labels in this screen.

Table 82 Configuration > Network > Routing Protocol > RIP

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	This field is available if the Authentication is Text. Type the
Authentication	password for text authentication. The key can consist of alphanumeric
Key	characters and the underscore, and it can be up to 8 characters long.
MD5	This field is available if the Authentication is MD5. Type the ID for
Authentication	MD5 authentication. The ID can be between 1 and 255.
ID
MD5	This field is available if the Authentication is MD5. Type the
Authentication	password for MD5 authentication. The password can consist of
Key	alphanumeric characters and the underscore, and it can be up to 16
	characters long.
Redistribute
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	Select this to use RIP to advertise routes that were learned through
Route	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.

14.3 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
