wfRipInterfacePoisonedReversed 1.3.6.1.4.1.18.3.5.3.2.2.1.1.9

Specifies how the router advertises routes it has learned from a neighboring router in periodic updates subsequently sent to the neighbor. If 'Poisoned', the node implements poisoned reverse. The router now advertises routes learned from a neighbor in RIP updates subsequently sent to that neighbor with a hop count of wfRipBaseRipNetworkDiameter plus 1, (thus declaring the destination unreachable). If 'Split', the router implements a split-horizon, and omits routes learned from a neighbor in RIP updates subsequently sent to that neighbor. If 'Actual', the learned cost of the route is advertised.
