ether1 of router A is connected to ether 1 of router B. Both routers have multiple devices connected that send multicast packets.
I have disables HW offloading on all bridge ports on both devices to capture these packets.
On router A:
On router B:
You can see how the multicast traffic is flooded on all ports, including ether1, but it doesn’t arrive on the other router.
I have also sent a unicast packet and you can see how it travels successfully through both devices.
Is there anything on the Mikrotik side that could cause this? The devices are factory config, I just created the bridge and added the ports to the bridge.
Now, the connection between router A and router B isn’t just an ethernet cable, it’s a powerline connection. I’m suspecting those powerline adapters might be eating multicast traffic?
Could I maybe configure the Mikrotiks so that they encapsulate the multicast traffic in a way that the powerline adapters don’t see them as multicast and leave them alone?
