By default, the device does not learn default RIP routes.
RIP router configuration mode or interface configuration mode.
The
no form of the command disables learning of default RIP routes.
The configurations at the global level and interface level are independent. Disabling or enabling one will not affect the other. When global level configuration is enabled, default routes are learned from all the interfaces. If global "learn-default " is not enabled but the interface-level "learn-default" is enabled, default routes are allowed from that rip interface. If "learn default" is not enabled for an interface, then the learned default routes for that interface are discarded.
The following example enables learning of default RIP routes globally.
device# configure terminal device(config)# router rip device(config-rip-router)# learn-default
The following command output shows RIP default routes are learned globally.
device(config)# show ip rip

The following example enables learning of default RIP routes on Ethernet interface 1/1/6.
device# configure terminal device(config)# interface ethernet 1/1/6 device(config-if-e10000-1/1/6)# ip rip learn-default
The following command output shows that RIP default routes are learned for the interface.
device(config)# show ip rip interface ethernet 1/1/16
