A directed broadcast is an IP broadcast to all devices in a directly attached network or subnet.
When a device receives a packet with "Broadcast IP" as the destination address and IP directed broadcast is enabled on a Layer 3 interface, the interface floods the packet to all devices in the directly attached destination network.
IP directed broadcast is supported on default and user-defined VRF.
By default, IP directed broadcast is disabled. You can enable it on a Layer 3 physical Ethernet interface or VE interface. This task uses an Ethernet interface as an example.
