Arun, IF you have an LSR, as you mentioned, A ---> B ---> C, then the packets under MPLS will be enroute this exact path. However, if there is a lower layer VLAN setup, which for policy reason redirects the packet through different paths. Even then at the MPLS layer the other path would be unknown.
