In the destination IP address of such a packet, the network ID field contains the network ID of a specific network, and the host ID field contains all 1s. To enable an interface to receive and forward directed broadcast packets destined for its direct network segment, run the ip forward-...

address is a broadcast address or not. If the interface of R1, which is connected to sw1, is configured with for example ip address 10.1.0.1/8 (10.1.0.1 with netmask 255.0.0.0), if will decide to send the packet as broadcastn because the target address is the broadcast address of the...

Windows 7 only sends global IP broadcast packets (destination address255.255.255.255) on the interface which matches the preferred route for255.255.255.255in the route table. More often than not, this isn't what you want: software that makes use of global broadcast packets (e.g. server browsers...
