We review the gamma-ray variability properties of AGN with the jet not directly pointing towards us, i.e. Misaligned AGN (MAGN). This class is mainly populated by nearby low power radio galaxies (i.e. FRIs). The high power radio sources (i.e. FRIIs) are indeed rare in the GeV sky.  The cause of the different FRI/FRII detection rate is still under debate, although different beaming/jet structural properties could explain the observations. The Fermi-LAT inspection of MAGN light curves collected in 4years of FERMI-LAT survey reveals FRI-FRII different temporal behaviors (confirming a radio galaxy dichotomy) and provides new insights into the location/dimension of the gamma-ray dissipation regions.
