Figure 1. Host A sends an Ethernet frame to Host B on LAN segment 1
As the bridge receives the Ethernet frame on bridge interface 1, it determines that Host A is attached to
bridge interface 1 and creates a mapping between the MAC address of Host A and bridge interface 1 in its bridge
table, as shown in Figure 2.
Figure 2 The bridge determines that Host A is attached to interface 1
When Host B responds to Host B, the bridge also hears the Ethernet frame from Host B. As the frame is
received on bridge interface 1, the bridge determines that Host B is also attached to bridge interface 1, and creates a
mapping between the MAC address of Host B and bridge interface 1 in its bridge table, as shown in Figure 3.
