Devices on ether1 and ether2 need to send tagged packets with VLAN-ID 99 in order to reach the host on ether3 (other packets do not get passed towards VLAN interface and further bridged with ether3). We can see in the host table that bridge2 has learned these hosts. Packets coming from ether3 to ether1 will be correctly sent out tagged and traffic will not be flooded in bridge1. But since MAC learning is only possible between bridge ports and not on interfaces that are created on top of the bridge interface, packets sent from ether2 to ether3 will be flooded in bridge1.
