Scenario2IGMPQuery
Fig 7-2 The switches as IGMP Queriers
The configuration of Switch2 is the same as the switch in scenario 1, Switch1 takes the
place of Multicast Router in scenario 1. Let’s assume VLAN 60 is configured in Switch1,
including port 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 enable
in Global mode and in VLAN60.
The configuration steps are listed below:
Switch1#config
Switch1(Config)#ip igmp snooping
Switch1(Config)#ip igmp snooping vlan 60 query
Switch2#config
Switch2(Config)#ip igmp snooping
Switch2(Config)#ip igmp snooping vlan 100
Switch2(Config)#ip igmp snooping vlan 100 mrouter interface ethernet 1/1
