Broadcast relay
When you configure broadcast relay, the router forwards broadcast packets across interfaces.
You can configure broadcast relay types including directed broadcast forwarding, NetBIOS
rebroadcast, and DHCP and BOOTP client broadcast.

Directed broadcast forwarding
About this task
A directed broadcast is an IP packet whose destination address is the broadcast address of a
network or subnet. A directed broadcast causes every host on the network to respond. You
can use directed broadcasts to obtain a list of all active hosts on the network. A hostile user
can exploit directed broadcasts to launch a denial-of-service attack on the network. For each
interface on the Branch Gateway, you can configure whether the Branch Gateway forwards
directed broadcast packets to the network address or subnet mask address of the interface.
Procedure
Enter
ip directed-broadcast
to enable directed broadcast forwarding on an
interface. Use the
no
form of this command to disable directed broadcast forwarding
on an interface.
