Hi
Assuming that I have three nodes in the network A, B, C such that A is connected to B and B is connected to C, but A and C are not directly connected but only through B. Will it be possible to send an MPI message from A to C by the Intel MPI framework such that B will route it automatically?

No, Intel MPI cannot route it automatically. Intel MPI library relies on OS or a driver or whatever, so direct connection between A and C has to be transparent.
