What does this linux command mean “route add -net 224.0.0.0 netmask 240.0.0.0 eth0”

Could somebody explain what exactly this command means in relation to transmitting and receiving multicast traffic

route add -net 224.0.0.0 netmask 240.0.0.0 eth0

The “224.0.0.0″ is a reserved range of IPv4 addresses having special multicast meaning (IPv4 Multicast).

The command in itself just means that the multicast routing should go through the “eth0″ interface.
