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.
Exercise caution when applying an
offset
command to routers on a broadcast network, as the router using
the
offset
command is modifying RIP advertisements before sending out those advertisements.
The
distance
command also allows you to manipulate route metrics. To assign different weights to routes
so that the ones with the lower weight or administrative distance assigned are preferred, use the
distance
command.
To set route matrixes, use the following commands.
