5.

Otherwise, filter (do not forward) the frame.

For instance, in Figure 9-5, the network has been migrated to use a switch. The switch’s

bridging table already has been populated with all the MAC addresses in the network. Fred

sends another frame to Barney. The switch knows that Barney is located off his E1 port, so

the switch forwards the frame out E1.
