MAC Broadcast

Hi Guys, just a quick query regarding ARP's.

I understand that when an arp request goes out to find a mac address that the Ethernet frame is and the MAC address is FFFF.FFFF.FFFF. But I was just wondering. Is their another MAC address included with this frame for the actual recipient? I suppose their must be or the sender would never get the response. Just curious anyway.

    Every frame contains a Source and Destination mac address.

    well to my knowledge arp requests can only be sent between switches or layer 2 devices, no broadcast is forwarded by routers based on mac addresses. And switches work on mac addresses, when it receive a broadcast frame it broadcast that frame to every port except from which it have received the frame. All switches do the same and every device in the network gets the frame, so there is no desti address needed but to find actual host we have ip address of the destination from which we are expecting mac address in reply. Hope this helpsicon_rolleyes.gif.
