Layer 3 Routing Commands 1534
Example
In the following example, the load sharing mode is configured to use the
destination IP addresses. This might be appropriate for distributing traffic
destined to be a set of servers with different IP addresses but deploying
identical services as determined by the destination port number.
console(config)# ip load-sharing 2
ip directed-broadcast
Use the ip directed-broadcast command in Interface Configuration mode to
enable the forwarding of network-directed broadcast packets on an interface
or range of interfaces. When enabled, network directed broadcasts are
forwarded. When disabled they are dropped. Use the no form of the
command to disable the broadcasts.
This command deprecates and replaces the ip netdirbcast command.
Syntax
ip directed-broadcast
no ip directed-broadcast
Default Configuration
Forwarding of network directed broadcast packets is disabled by default.
Command Mode
Interface (VLAN) Configuration mode
User Guidelines
Enabling this command may make a network vulnerable to flooding or ARP
table poisoning man-in-the-middle attacks. It is recommended that ACLs be
deployed on uplinks to limit the originating addresses of network-directed
broadcast packets to known hosts.
Example
The following example defines the IP address and subnet mask for VLAN 15.
console(config)#interface vlan 15
console(config-if-vlan15)#ip directed-broadcast
