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 Dell Networking OS does globally (shown in bold).

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 Dell Networking OS, 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.
– value The range is from 1 to 16.
– route-map-name: The name of a configured route map.
To confirm that the default route configuration is completed, use the show config command in ROUTER RIP mode.
Summarize Routes
Routes in the RIPv2 routing table are summarized by default, thus reducing the size of the routing table and improving routing
efficiency in large networks.
By default, the autosummary command in ROUTER RIP mode is enabled and summarizes RIP routes up to the classful network
boundary.
If you must perform routing between discontiguous subnets, disable automatic summarization. With automatic route
summarization disabled, subnets are advertised.
The autosummary command requires no other configuration commands. To disable automatic route summarization, enter no
autosummary
in ROUTER RIP mode.
NOTE: If you enable the ip split-horizon command on an interface, the system does not advertise the summarized
address.
