As shown above, Host A and Host C can receive multicast data.
Configuring simulated joining
Configure simulated joining on Switch B, thus to prevent the multicast switch from considering that no multicast receiver exists on the subnet due to some reasons and pruning the corresponding path from the multicast forwarding tree.
# Configure Ethernet 1/0/21 as a simulated host to join multicast group 225.1.1.1.
