Please have a look at PimMrt::receive_data() inside pim/pim_mrt_mfc.cc .
Despite its name, it implements the logic (as specified in the spec)
when data packet is received, but in reality it is not called per
data packet. It is called only when certain events occur.
Pay close attention when the PimMfc::update_mfc() method is called
which does the job of (re)calculating and installing the forwarding
entry.
