Send Version – The RIP version to send on an interface.
-RIPv1: Sends only RIPv1 packets.
-RIPv2: Sends only RIPv2 packets.
-RIPv1 Compatible: Route information is broadcast to other
routers with RIPv2. (Default)
-Do Not Send: Does not transmit RIP updates.
(The default depends on the setting specified under RIP / General Settings,
Global RIP Version: RIPv1 - RIPv1 Compatible, RIPv2 - RIPv2 packets)
Instability Preventing – Specifies the method used to reduce the
convergence time when the network topology changes, and to prevent
RIP protocol messages from looping back to the source router.
(Default: Split Horizon)
-None: No method is used. If a loop occurs, the hop count for a
route may be gradually incremented to infinity (i.e., 16) before the
route is deemed unreachable.
-Split Horizon: This method never propagates routes back to an
interface from which they have been acquired.
-Poision Reverse: This method propagates routes back to an
interface port from which they have been acquired, but set the
distance-vector metrics to infinity. (This provides faster
convergence.)
Authentication Type – Specifies whether or not authentication is
required for exchanging protocol messages. (Default: No
Authentication)
-No Authentication: No authentication is required.
-Simple Password: Requires the interface to exchange routing
information with other routers based on an authorized password.
(Note that authentication only applies to RIPv2.)
Authentication Key – Specifies the key to use for authenticating
RIPv2 packets. For authentication to function properly, both the
sending and receiving interface must use the same password. (Range:
1-16 characters, case sensitive)
