When I use a broadcast IP address, for example 198.255.255.255, what will happen when it gets passed down to the link-layer which will then look for the corresponding MAC address in your ARP table. Does your ARP table have an entry for 198.255.255.255;FF:FF:FF:FF:FF:FF, if not, how can the link-layer know it should use FF:FF:FF:FF:FF:FF as physical address to broadcast it into the subnet?

Does your ARP table have an entry for 198.255.255.255;FF:FF:FF:FF:FF:FF?

Yes, it does if that is your network broadcast address. It will also have an entry for the Limited Broadcast address 255.255.255.255 relating to ff-ff-ff-ff-ff-ff.

You can see this if you show your ARP table (arp -a for Windows).
