• 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)
