How broadcast is created in switch ?
Answer: lets say when a switch recieves a frame from end
device (pc) it looks for the destination mac address in the
frame . and tallies it with the filter table .
(filter table : is a table witch has mac address of all the
devices in same subnet)
in case it doesnt finds the dest mac sddress in the table it
throws a broadcast to all the devices asking whos mac
address is it.. thats how it works.
