Switches
Figure K-9. Point-to-Multipoint using Switches
With switches used, the hub and remote are on the same subnet as shown in Figure K-9,
meaning that broadcasts will be allowed to transverse the network. Learning Mode must be
disabled on the Hub Tx/Rx modem, because if a computer on the remote sends a broadcast out
to the Hub, the modem learns that MAC is local – when, in fact, it is not.
