Bridge Overview 291
Figure 102 Bridge learns that Workstation A is connected with Port 1
Once Workstation B responds to Workstation A, the bridge can detect the
responding Ethernet frame from Workstation B and learn that Workstation B is
also connected to Bridge port 1 because the frame is detected on port 1 too. As a
result, the correlation between the MAC address of Workstation B and Bridge port
1 is added to the bridging table too, as shown in the following figure:
Figure 103 Bridge learns that Workstation B is connected with the port 1 too.
At last, given that all the workstations are in use, the bridge will obtain all
correlation between the MAC addresses and the bridge ports as shown in the
following figure:
