It does matter who the BDR is. You shouldn't have a BDR is this design. If
the hub is the DR and say spoke1 is the BDR when using physical interfaces
with frame-relay, what is going to happen when the hub gets rebooted?
Answer: Spoke1 will become the DR and when the hub comes back up it will see
that there already is a DR and no DR election will take place. Since spoke2
and spoke3 do not have direct communication with the DR (spoke1) your network
will be hosed.
