WebSplit Horizon + Poison Reverse •Advertise reverse routes with a metric of 16 (i.e., unreachable). •Does not add inormation but breaks loops faster •Adds protocol overhead … Poison Reverse is often used within distance-vector routing to solve the count-to-infinity problem. Practically, poison reverse can be thought of as an alternative to split horizon. With poison reverse, route advertisements that would be suppressed by split horizon are instead advertised with a distance of infinity. The basic idea of poison reverse is to make sure that a path does not turn bac…
