  We study the Josephson effect in $s_{\pm}/I/s_{\pm}$ junctions made by two
bands reversed sign s-wave ($s_{\pm}$) superconductive materials. We derive an
equation providing the bound Andreev energy states parameterized by the band
ratio $\alpha$, a parameter accounting for the weight of the second band with
respect to the first one at the interface. For selected values of the band
ratio and tunnel barrier amplitude, we predict various features of the
Josephson current, among which a possible high temperature $\pi$ state of the
junction (a doubly degenerate junction ground state) and a $\pi \rightarrow 0$
crossover with decreasing temperature.
