IP directed broadcast provides a method of sending broadcast packets to hosts on a
specified subnet without broadcasting those packets to hosts on the entire network.
This example shows how to enable a subnet to receive IP directed broadcast packets
so you can perform backups and other network management tasks remotely:
Requirements on page 1138
Overview and Topology on page 1139
Configuration on page 1139
This example uses the following software and hardware components:
Junos OS Release 9.4 or later for EX Series switches
One PC
One EX Series switch
Before you configure IP directed broadcast for a subnet:
Ensure that the subnet does not have a direct connection to the Internet.
Configure routed VLAN interfaces (RVIs) for the ingress and egress VLANs on the
switch. See "Configuring Routed VLAN Interfaces (CLI Procedure)" on page 1379 or
"Configuring VLANs for EX Series Switches (J-Web Procedure)" on page 1375.
