Configuration

Edit the configuration of the networking:

$ sudo vim /etc/network/interfaces
###########################################
## By using openVswitch, we enabled the following
###########################################
auto ovsbr0
iface ovsbr0 inet static
address 192.168.1.xx
netmask 255.255.0.0
gateway 192.168.1.xx
dns-nameservers 223.5.5.5 180.76.76.76

Now configure the ovs-switched bridge:

# ovs-vsctl add-br ovsbr0
# ovs-vsctl list-br
ovsbr0
# ovs-vsctl add-port ovsbr0 eth0 && reboot

Now restart the computer you will get the ovs-bridged network running.

Bridged With VLAN

Add/Remove port of the ovs-bridged:

# ovs-vsctl add-port ovsbr0 tap0 tag=22
# ovs-vsctl show
901c2b29-0764-4370-8d06-168b18339236
    Bridge "ovsbr0"
        Port "eth0"
            Interface "eth0"
        Port "tap0"
            tag: 22
            Interface "tap0"
        Port "ovsbr0"
            Interface "ovsbr0"
                type: internal
    ovs_version: "2.0.2"
# ovs-vsctl del-port ovsbr0 tap0

If you want to remove the tag, then:

ovs-vsctl set port vnet0 tag=100
ovs-vsctl remove port vnet0 tag 100
