ip rip split-horizon
This command enables split-horizon or poison-reverse (a variation) on an
interface. Use the no form to disable this function.

◆
Split horizon never propagates routes back to an interface from which
they have been acquired.
◆
Poison reverse propagates routes back to an interface port from which
they have been acquired, but sets the distance-vector metrics to
infinity. (This provides faster convergence.)
◆
If split-horizon is disabled with the no rip ip split-horizon command,
and a loop occurs, the hop count for a route may be gradually
incremented to infinity (that is, 16) before the route is deemed
unreachable.
E
XAMPLE
This example propagates routes back to the source using poison-reverse.
