Bridge Filters 1-21
Figure 1-19: A filter set for port 2 has been set up allowing device
A to communicate through the bridge and out of that port. No
other device can communicate through the bridge and out of that
port.
Figure 1-19 An Example Network With Filter Set
Figure 1-20: Device A transmits a packet for device C. The bridge
knows that device C is connected to port 2, so it checks that
port's filter set. Communication is allowed, so it forwards the
packet.
