-  * TAP1 - server side port that receives traffic
-  * Tunnel is created between TAP0 and TAP1 to transmit traffic to an external platform
-  * mac learning is disabled on the TAP0 interface
-Run the following commands from the console:
-<code bash>
-ip tuntap add tap0 mode tap
-ip tuntap add tap1 mode tap
-ip link set dev tap0 up
-ip link set dev tap1 up
-ip link add br0 type tunnel
-ip link set tap0 master br0
-bridge link set dev tap0 learning off
-ip link set tap1 master br0
-ifconfig tap0 192.168.4.20 up
