I've following scenario
Upper computer on VLAN 10 is sending some multicast messages and lower computer on VLAN 10 sends IGMP join periodically.
Lets say MC address is
Now, computer on VLAN 20 is sending IGMP join to
184.108.40.206 (IGMP snooping is configured).
Would the data arrive to the computer on VLAN 20? If so, is there some way to prevent that from happening?
