IGMP Snooping Configuration Examples

Configuring Simulated Joining

Network requirements

As shown in

Figure 29-3

, Router connects to the multicast source through GigabitEthernet 0/0/2 and to

AC through GigabitEthernet 0/0/1.

IGMPv2 is to run between Router and AC, and IGMPv2 Snooping is to run on AC. Router is the IGMP
querier on the subnet.

Perform the following configuration so that multicast data can be forwarded through GigabitEthernet
0/0/3 and GigabitEthernet 0/0/4 even if Host A and Host B temporarily stop receiving multicast data for
some unexpected reasons.
