Figure 42-5.  show ip protocols Command Example
Generate 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 the ROUTER RIP mode to generate a default route into RIP. In FTOS, default routes received 
in RIP updates from other routes are advertised if the 
default-information originate
 command is 
configured.
To configure FTOS to generate a default route, use the following command in the ROUTER RIP mode: 
Use the 
show config
 command in the ROUTER RIP mode to confirm that the default route configuration 
is completed.
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 the 
ROUTER RIP mode is enabled and summarizes RIP routes up to the classful network boundary.
