Figure 54 - Example-Directed broadcast forwarding disabled
In the example in Figure , directed broadcast forwarding is enabled on the
Master
unit and disabled
on the
Remote (1)
unit. If
Sender
sends a packet to destination address 172.30.1.255, the packet
would be discarded by
Remote (1
), it would not reach
Remote Host (1)
,
Remote Host (2),
and
Re-
mote Host (3)
.
If the user wants the
Master
unit to do the discarding of the directed broadcast packets, then the di-
rected broadcast forwarding must be disabled on the
Master
unit itself.
LIMITED BROADCAST
The “
Limited Broadcast
” radio buttons let the user select whether the unit must forward or not
limited
broadcast
packets. Upon reception of a
limited broadcast
packet, the unit takes the following actions:
•
Keeps a copy for itself (passes to internal applications, if any).
•
If
limited broadcast
packets can be forwarded:
Sends a copy of the packet from all interfaces except
from the one that received the packet.( i.e. if the packet was received by Ethernet Interface, it will be
sent out by RF Interface and vice versa)
•
If
limited broadcast
packets cannot be forwarded:
Silently discards the packet.
