I have created a dummy interface (vnet), I have assigned a MAC address, an ip address, and I have added it to br_untagged bridge (see image). The state of the interface in the bridge is FORWARDING. I have also added a default route to a fake ip from the interface. I ping from the interface to the address that I added,but when I do tcpdump in the br_untagged and I do not see the traffic.
If you need more info, i can add it.
Thanks. My scheme
