port 2, 6, 10 plays program1, while the host is connected to port 12 plays program 2.
IGMP Snooping listening result:
The multicast table built by IGMP Snooping in VLAN 100 indicates ports 1, 2, 6, 10 in
Group1 and ports 1, 12 in Group2.
All the four hosts can receive the program of their choice: ports 2, 6, 10 will not receive
the traffic of program 2 and port 12 will not receive the traffic of program 1.
Scenario 2. IGMP Query
Fig 14-2 The switches as IGMP Queries
The configuration of Switch2 is the same as the switch in scenario 1, SwitchA takes the
place of Multicast Router in scenario 1. Let’s assume VLAN 60 is configured in SwitchA,
including ports 1, 2, 6, 10 and 12. Port 1 connects to the multicast server, and port 2
connects to Switch2. In order to send Query at regular interval, IGMP query must
enabled in Global mode and in VLAN60.
The configuration steps are listed below:
SwitchA#config
SwitchA(Config)#ip igmp snooping
