This occurs when a link prefix route points to a point-to-point link, a destination IPv6 address belongs to the prefix and is not a local IPv6 address, and a router advertisement is received with at least one global unique IPv6 prefix for which the on-link flag is set."

Esto ocurre cuando una ruta de prefijo de enlace apunta a un enlace punto a punto, una direcci\u00f3n IPv6 de destino pertenece al prefijo y no es una direcci\u00f3n IPv6 local, y un anuncio de enrutador es recibido con al menos un prefijo IPv6 \u00fanico global para el cual el flag on-link se establece"
