How will relay agent gets the source mac ?Source will create the packet as :-

Data | 0.0.0.0 | 255.555.555 .

How will now relay agent gets the MAc address. Is it DLL layer which encapsulates this packet at source  put Mac or something else?
Packet is further encapsulated by DLL header and CRC trailer
and DLL header has source and destination MAC.
 
A Frame encapsulates packet and this frame is actually transmitted.
Remember OSI hierarchy

source will create--> Data | 0.0.0.0 | 255.555.555  at NL, at DLL packet will look like,

IP_packet | MACsource | 255.255.255.255.255.255 and transfered to relay agent...

Thanks
