Scenario 2 IGMP L2-general-querier
Fig 11-2 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.
