Example (Limited Broadcast forwarding disabled)

Figure 36 - Example of Limited broadcast forwarding disabled

In this example (Figure 36), limited broadcast forwarding is enabled on the Base unit, disabled on the

Mobile (1) unit and enabled on the Mobile (2) unit. If Sender sends a packet to destination address

255.255.255.255, the packet would reach Mobile Host (4) only

. The Mobile (1) unit would discard

any limited broadcast packet it received from the Base unit.

If the user wants the Base unit to do the discarding of the limited broadcasting packets, then the lim-

ited broadcast forwarding must be disabled on the Base unit itself. Then no Mobile Host unit would

ever be receiving a limited broadcast packet.
