Setup Guide

The following example shows the RIP conguration after the ROUTER RIP mode version command is set to RIPv2. When you set the
ROUTER RIP mode version command, the interface () participating in the RIP process is also set to send and receive RIPv2 (shown
in bold).
To view the routing protocols conguration, use the show ip protocols command in EXEC mode.
To congure 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.
DellEMC(conf-if)#ip rip send version 1 2
DellEMC(conf-if)#ip rip receive version 2
The following example of the show ip protocols command conrms that both versions are sent out that interface. This interface no
longer sends and receives the same RIP versions as Dell EMC Networking OS does globally (shown in bold).
Generating a Default Route
Trac is forwarded to the default route when the trac’s network is not explicitly listed in the routing table.
Default routes are not enabled in RIP unless specied. Use the default-information originate command in ROUTER RIP mode
to generate a default route into RIP. In Dell EMC Networking OS, default routes received in RIP updates from other routes are advertised if
you congure 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 congured route map.
To conrm that the default route conguration 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 eciency 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 conguration 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 dierent route, manipulate the route by using the offset command.
