Computers A and and B are connected to the same switch. A is in subnet 192.168.1.0/24, B in 192.168.2.0/24, so they cannot communicate directly using unicast. But what about multicast communication? Will it work or not?

There are no other devices or software here which could help with packet routing.

  • just to fully understand, why both computers are configured in 2 different subnets, if they are supposed to be able to communicate, and there is no routing solution ? – Chaoxiang N Mar 02 '19 at 16:07
  • @ChaoxiangN: They should not communicate together. I have concerns that both computers may try to use the same multicast address for their own purposes, and may inadvertently disrupt each other. – Daniel Frużyński Mar 02 '19 at 19:04

If A and B are in the same VLAN on that switch then both multicast and certain types of broadcast will be seen by both.
