English term or phrase: Route poisoning
Esta es la frase. Es un curso de routers de Cisco.

¿Existe una traducción estándar para este término?

Route poisoning is used by various distance vector protocols in order to overcome large routing loops and offer explicit information when a subnet or network is not accessible.

envenenamiento de ruta
Explanation:

Cuando tiene lugar un fallo de línea o un cambio WAN, como la hora del día, el Orbitor pierde la conexión, todas las rutas que emplean ese enlace resultan "envenenadas" (lo que se denomina envenenamiento inverso). Esto se hace retransmitiendo la ruta o rutas "perdidas" con un contador de salto de 16, indicándole a cada router que la ruta está allí pero no es funcional. Tras 3 retransmisiones de este tipo, el Orbitor deja de retransmitir las rutas envenenadas hasta que se aprende una nueva ruta o el enlace se restablece.

ROUTE POISONING:

When a network link goes down, neighbour routers advertise a (IP + IPX) HOP count of 16 (Destination Unreachable) for that network.

Route poisoning is a method of preventing a network from sending packets through a route that has become invalid. When the routing protocol detects an invalid route (such as can be caused by a severed cable or the failure of a network node), all of the routers in the network are informed that the bad route has a hop count of 16, which stands for infinity. This makes all nodes on the invalid route appear infinitely distant, thereby preventing any of the routers from sending packets over the invalid route.

Cisco also deploys so-called route poisoning. This technique is used, upon learning about the unreachable destination, to advertise the information on the failed route by sending a route update with an infinite metric.

Poison reverse is usually used in conjunction with split horizon; thus the mechanisms work together to prevent routing loops (a potential danger with distance vector routing). Poison reverse is also used in conjunction with holddown timers.
