I want to solve a linear system, which has the following form

(A+B A^{-1} B) u = f

Here A is a diagonal black matrix, B is a block matrix that I can figure 
out the pattern. Are there any solver that I can use to solve the linear 
system?

or 

Can I figure out the pattern of B*B or BA^{-1}B ?

Best,
