Figure 10.4 IGMP Snooping Example
As a result of this configuration, the queries received on the router by Ethernet
1/1 will not be forwarded to Ethernet 0/1 and Ethernet 2/1. The router itself
will reply back with Membership report message. However, if you do not
enable Proxy on the router, when it receives a IGMP Query message on
Ethernet 1/1, it forwards it to both Host A and Host B. As a result, both the
hosts reply with a Membership report(as Layer-2 IGMP is running on the
hosts).
Since Host A and Host B are members of the same Multicast group, the router
is not notified when Host A leaves the group, as the group still has another
member Host B remaining. When Host B also leaves the group, the router will
send a Leave message to the Router with the destination address as 224.0.0.2
(All Router Destination Address).
