Advanced Configuration Example: IGMP Snooping
shows an example topology. Switches B and C are configured with IGMP
Snooping.
Figure 20. Topology
Devices in this topology are configured as follows:
•
STG2 includes VLAN2; STG3 includes VLAN3.
•
The multicast server sends IP multicast traffic for the following groups:
– VLAN 2, 225.10.0.11 – 225.10.0.12, Source: 22.10.0.11
– VLAN 2, 225.10.0.13 – 225.10.0.15, Source: 22.10.0.13
– VLAN 3, 230.0.2.1 – 230.0.2.2, Source: 22.10.0.1
– VLAN 3, 230.0.2.3 – 230.0.2.5, Source: 22.10.0.3
•
The Mrouter sends IGMP Query packets in VLAN 2 and VLAN 3. The Mrouter’s
IP address is 10.10.10.10.
•
The multicast hosts send the following IGMP Reports:
– IGMPv2 Report, VLAN 2, Group: 225.10.0.11, Source: *
– IGMPv2 Report, VLAN 3, Group: 230.0.2.1, Source: *
– IGMPv3 IS_INCLUDE Report, VLAN 2, Group: 225.10.0.13, Source:
22.10.0.13
– IGMPv3 IS_INCLUDE Report, VLAN 3, Group: 230.0.2.3, Source: 22.10.0.3
