43.10.3 IGMP Snooping Examples
Scenario 1: IGMP Snooping function
Figure 43-10 Enabling IGMP Snooping function
Example: As shown in the above figure, a VLAN 100 is configured in the switch and includes ports 1, 2, 6, 10
and 12. Four hosts are connected to port 2, 6, 10, 12 respectively and the multicast router is connected to port
1. As IGMP Snooping is disabled by default either in the switch or in the VLANs, If IGMP Snooping should be
enabled in VLAN 100, the IGMP Snooping should be first enabled for the switch in Global Mode and in VLAN
100 and set port 1 of VLAN 100 to be the mrouter port.
The configuration steps are listed below:
Switch(config)#ip igmp snooping
Switch(config)#ip igmp snooping vlan 100
Switch(config)#ip igmp snooping vlan 100 mrouter interface ethernet 1/1
