Figure 61: RIP interface configuration
Interface
The FortiGate interface name.
Send Version
RIP routing messages are UDP packets that use port 520.
Select 1 to configure RIP to send RIP version 1 messages from an
interface.
Select 2 to configure RIP to send RIP version 2 messages from an
interface.
Select Both to configure RIP to send both RIP version 1 and RIP version
2 messages from an interface.
Setting the Send Version here overrides the default RIP version for this
interface.
Receive Version
RIP routing messages are UDP packets that use port 520.
Select 1 to configure RIP to listen for RIP version 1 messages on an
interface.
Select 2 to configure RIP to listen for RIP version 2 messages on an
interface.
Select Both to configure RIP to listen for both RIP version 1 and RIP
version 2 messages on an interface.
Setting the Receive Version here overrides the default RIP version for
this interface.
Split-Horizon
Configure RIP to use either regular or poisoned reverse split horizon on
this interface.
Select Regular to prevent RIP from sending updates for a route back out
the interface from which it received that route.
Select Poisoned reverse to send updates with routes learned on an
interface back out the same interface but with the routes marked as
unreachable.
Authentication
Select the authentication used for RIP version 2 packets sent and
received by this interface. If you select None, no authentication is used. If
you select Text, the authentication key is sent as plain text. If you select
MD5, the authentication key is used to generate an MD5 hash.
Both text mode and MD5 mode only guarantee the authenticity of the
update packet, not the confidentiality of the routing information in the
packet.
In text mode the key is sent in clear text over the network. Text mode is
usually used only to prevent network problems that can occur if an
unwanted or misconfigured router is mistakenly added to the network.
