We do not need to create separate bridges for each VLAN, like Linux bridges. Configuring an Open vSwitch bridge is a little more complicated than a Linux bridge. We need to configure the port first before creating the actual bridge. In our example, we are going to configure the port, eth1, which is what our Open vSwitch bridge, vmbr1, is going to be based on. For this, we need to add the following lines of code to /etc/network/interfaces:
