Broadcast frame
In Ethernet networks, a frame that has a hexadecimal MAC address of
FF-FF-FF-FF-FF-FF. This hexadecimal address is equivalent to 48
binary “ones.” The meaning of this address in Ethernet is simply that
this frame is intended to be received and processed by every node on
the network of computers. Broadcast frames are generated when
certain network services need to make announcements to other hosts on
the network. Too many broadcast frames on a network can degrade
communication between nodes on the network.
NOTE
Most
routers are not configured to forward broadcast frames to other
subnets in an internetwork; therefore, broadcast frames used as
announcements are limited in scope to the local subnet on which the
broadcasting host is located.
