Figure 38-2: 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, 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
SwitchA(config)#ip igmp snooping vlan 60
SwitchA(config)#ip igmp snooping vlan 60 L2-general-querier
SwitchB#config
SwitchB(config)#ip igmp snooping
SwitchB(config)#ip igmp snooping vlan 100
SwitchB(config)#ip igmp snooping vlan 100 mrouter interface ethernet 1/1
