Figure 286 Forwarding
• When Host A sends an Ethernet frame to Host B, as Host B is on the same LAN segment with
Host A, the bridge filters the Ethernet frame instead of forwarding it, as shown in Figure 287.
Figure 287
Filtering
• When Host A sends an Ethernet frame to Host C, if the bridge does not find a MAC-to-interface
mapping about Host C in its bridge table, the bridge forwards the Ethernet frame to all interfaces
except the interface on which the frame was received, as shown in Figure 288.
