To configure an interface to receive or send both versions of RIP, include 1 and 2 in the command syntax. The command
syntax for sending both RIPv1 and RIPv2 and receiving only RIPv2 is shown in the following example.
Example of Configuring an Interface to Send/Receive Specified Versions of RIP
FTOS(conf-if)#ip rip send version 1 2
FTOS(conf-if)#ip rip receive version 2
The following example of the show ip protocols command confirms that both versions are sent out that interface.
This interface no longer sends and receives the same RIP versions as FTOS does globally (shown in bold).
Example of the show ip protocols Command to Verify RIP Versions on an Interface
FTOS#show ip protocols
Routing Protocols is RIP
Sending updates every 30 seconds, next due in 11
Invalid after 180 seconds, hold down 180, flushed after 240
Output delay 8 milliseconds between packets
Automatic network summarization is in effect
Outgoing filter for all interfaces is
Incoming filter for all interfaces is
Default redistribution metric is 1

Generating a Default Route
Traffic is forwarded to the default route when the traffic’s network is not explicitly listed in the routing table.
Default routes are not enabled in RIP unless specified. Use the default-information originate command in
ROUTER RIP mode to generate a default route into RIP. In FTOS, default routes received in RIP updates from other routes
are advertised if you configure the default-information originate command.
• Specify the generation of a default route in RIP.
ROUTER RIP mode
default-information originate [always] [metric value] [route-map route-map-
name]
– always: Enter the keyword always to always generate a default route.
