■ LS_B is connected to LS_A through Vlan-interface 10, to LS_C through
Vlan-interface 11 and to LS_D through Vlan-interface 12.
■ LS_C is connected to Host B through Vlan-interface 10, to LS_B through
Vlan-interface 11 and to LS_A through Vlan-interface 12.
Host A is the receiver of the multicast group whose multicast IP address is
225.0.0.1. Host B begins to send data to the destination 225.0.0.1 and LS_A
receives the multicast data from Host B through LS_B.
