As shown in Figure 1-24, a non-IP Multicast filtering switch causes IP Multicast
traffic to be sent to all segments on the local subnet.
Figure 1-24. IP Multicast Propagation with IGMP Routing
The BayStack 350 10/100/1000 Series Switches can automatically set up IP
Multicast filters so the IP Multicast traffic is only directed to the participating end
nodes (see Figure 1-25
).
In Figure 1-25
, switches S1 to S4 represent a LAN connected to an IP Multicast
router. The router periodically sends Host Membership Queries to the LAN and
listens for a response from end stations. All of the clients connected to switches
S1 to S4 are aware of the queries from the router.
