RARP (Reverse Address Resolution Protocol ) client (say ,Host A) sends a request packet with broadcast MAC Address and receive an IP in reply. 

RARP request packet at NL

Ma      0 . 0 . 0 . 0


RARP request packet at DLL

                                                                                                            Source MAC                Dest. MAC                            

Ma    0 . 0 . 0 . 0


    Ma   ALL 1's

Since , All 1's broadcast MAC adress.

RARP reply packet from RAPR server. 

At Network layer:

Ma     IP address of A


                                                                                                           Source MAC                Dest. MAC                            

Ma  IP address of A


     RARP server MAC                       address            Ma
