rip output

Description
Use the 
rip split-horizon
 command to configure an interface to use split 
horizon when transmitting RIP packets. This is the default.
Use the 
undo rip split-horizon
 command to configure an interface not to use 
split horizon when transmitting RIP packets. 
Normally, split horizon is necessary for preventing router loops. You may need to 
disable split horizon to ensure proper operation of protocols.
