As shown in 

z 

Router A connects to a multicast source through port GigabitEthernet 2/0/2, and to Switch A 

through port GigabitEthernet 2/0/1. 

z 

Router A runs IGMPv2 and Switch A runs IGMPv2 Snooping. Router A serves as an IGMP querier.  

Configure IGMP snooping proxying on Switch A, enabling the switch to forward IGMP reports and leave 

messages on behalf of attached hosts and to respond to IGMP queries from Router A and forward the 

queries to the hosts on behalf of Router A.
