Connect Ethernet 2/0/1 of the switch with a multicast source, and connect port OLT 3/0/1 of the 
OLT with an ONU, which is bound to ONU 3/0/1:1, through an optical splitter. Attach two hosts, 
User 1 and User 2, to ports UNI 1 and UNI 2 respectively.  

 

It is required that User 1 has access to channels from 225.1.2.1 to 225.1.2.255, and User 2 has 
access to channels from 225.1.3.1 to 225.1.3.255.
