Configuration of two message buffer(MB) for reception with same ID !

According to MPC5668 datasheet,
each Flexcan module has 64 MB (Message Buffers), each of them being configurable
for reception or transmission. Each MB has an ID field to allow reception of
frames which ID is the same as the one configured in the MB. I would like to
know what happens if two MB configured for reception are initialized with same
ID? A frame is received in both MB at the same time or only one MB will receive
the frame and what is the associated arbitration method?

 

thank you
