Configuring and Customizing IP

Enabling Directed Broadcast on a Router
A directed broadcast is a broadcast sent to an entire network. For example, when
directed broadcast is enabled, a packet addressed to an IP broadcast address goes
to all systems on the target network. By default, directed broadcast is enabled.
To globally disable or reenable directed broadcast, go to the global IP prompt (for
example,
box;
ip
) and enter:
directed-bcast
<state>
state
is one of the following:
enabled
(default)
disabled
For example, the following command disables directed broadcast on a router:
ip#
directed-bcast disabled
Caution:
Internet service providers have reported forged ICMP echo request
packets sent to IP addresses (SMURF attacks), sometimes resulting in severe
network congestion. To prevent these attacks, directed broadcast must be
disabled.
