  The aim of this work is to apply the dynamical system approach to study the
linear dynamics of the normal DGP brane-world model with agegraphic dark
energy. The stability analysis of the model will be investigated and the phase
plane portrait will be illustrated. The nature of critical points will be
analyzed by evaluating the eigenvalues of a linearized Jacobi matrix. Also, the
statefinder diagnostic procedure will be applied to show the slight deviation
from the {\Lambda}CDM model. One of the most interesting results of this work
is the great alleviation of the coincidence problem.
