Poison Reverse is a technique used in routing protocols where a router sends a route back to the neighbor it received it from, with an infinite metric, to prevent routing loops in a network.
Poison Reverse Definition: Poison Reverse is a technique used in routing protocols where a router sends a route back to the neighbor it received it from, with an infinite metric, to prevent routing loops in a network.
Poison Reverse is a technique in computer networking where a router informs its neighboring routers that a specific route is unreachable by advertising a reverse metric value equal to infinity (or a very high value). This is used to prevent routing loops in distance-vector routing protocols by indicating that the advertised route should not be used for forwarding packets.
