RIP Configuration Terms and Definitions

Term	Definition
Routing Information Protocol (RIP)	A distance-vector routing protocol for use in small networks that broadcasts route updates at set intervals using a hop metric to determine route preference.
distance	An administrative value that sets the preference for the routing protocols on this device.
RIP offset	A value that is added to the hop metric of an incoming or outgoing route learned by RIP for the configured interface.
update interval	Sets the interval that determines the frequency of routing updates.
expiration interval	Sets the interval that determines the expiration of a route based upon the point of the last update.
flush interval	Sets the interval for the deletion of an expired route based upon the point of expiration.
key chain	A named chain that holds RIP authentication keys.
key	A key chain member that contains the key string used to authenticate RIP packets, accept-lifetime, and send-lifetime.
key string	A text string that is sent with RIP packets which must agree at both ends of the transmission for authentication to take place.
accept-lifetime	Specifies the time period during which an authentication key on a key chain is valid to be received by this device.
send-lifetime	Specifies the time period during which an authentication key on a key chain is valid to be sent by this device.
passive-interface	An interface configured to not transmit RIP update packets.
