Figure 25. IGMP Snooping Querier Example 1

The next example adds a second switch that has the same VLAN, the
Default VLAN. IGMP snooping is enabled on the switch so that it can build
its list of nodes for the multicast group. Since a LAN can have just one
querier, IGMP snooping querier is not enabled on switch 2, making a
routing interface unnecessary.
