Planet Networking & Communication WGSW-50040 Configuration Manual page 165

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
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
Multicast Configuration
The same as scenario 1
IGMP Snooping listening result:
Similar to scenario 1
Scenario 3: To run in cooperation with layer 3 multicast protocols.
SWITCH which is used in Scenario 1 is replaced with ROUTER with specific configurations remains the same.
And multicast and IGMP snooping configurations are the same with what it is in Scenario 1. To configure
