Based on network performance, you need to make RIP timers of RIP routers identical to each other to 
avoid unnecessary traffic or route oscillation. 
 
Configuring Split Horizon and Poison Reverse 
 
 
If both split horizon and poison reverse are configured, only the poison reverse function takes effect. 
 
The split horizon and poison reverse functions can avoid routing loops.  
Enabling split horizon 
The split horizon function disables an interface from sending routes received from the interface to 
prevent routing loops between adjacent routers. 
Follow these steps to enable split horizon:

Disabling the split horizon function on a point-to-point link does not take effect. 
 
Enabling poison reverse 
The poison reverse function allows an interface to advertise the routes received from it, but the metric of 
these routes is set to 16, making them unreachable. 
Follow these steps to enable poison reverse:
