# dockers with tagged vlans over tap0

Hello, i created a small demo to join two containers in vlans over tap0

and i don’t understand why vlan_test1 and vlan_test2 don’t see each other . In case if parent interface is removed i.e. with a fully internal network they see each other.

Is this a bug? I don’t see anything that contradicts to:

I need such configuration as it will be extended with qemu instance with attached tap0 and i want to install vlan here as well
