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.
Controlling Route Metrics
As a distance-vector protocol, RIP uses hop counts to determine the best route, but sometimes the
shortest hop count is a route over the lowest-speed link.
To manipulate RIP routes so that the routing protocol prefers a different route, manipulate the route by
using the offset command.
