EES4710BD 10 Slots L2/L3/L4 Chassis Switch
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 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:
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
Multicast Configuration
The same as scenario 1.
IGMP Snooping listening result:
Similar to scenario 1.
