Silicon Band Structure for both ibrav 0 and ibrav 2

I did scf and bands for silicon using both ibrav=0 and ibrav 2 After running the two bands separately I noticed that the band structures for the two (ibrav 0 and ibrav 2) were totally difference but in literature i read that the two (both ibrav 0 and ibrav 2) should give the same result. For Ibrav 2 band structure gave correct stucture while ibrav 0 gave wrong structure. Please what should i do to ensure that the two band structures are the same. Thanks in anticipation
