  The aim of this work is to study numerically the interaction of large
amplitude solitary waves with an external periodic forcing using the forced
extended Korteweg-de Vries equation (feKdV). Regarding these interactions, we
find that a solitary wave can bounce back and forth remaining close to its
initial position when the forcing and the solitary wave are near resonant or it
can move away from its initial position without reversing their direction.
Additionally, we verify that the numerical results agree well within the
asymptotic approximation for broad the forcings.
