VTN renderer using NIC

This section will demonstrate how VTN works using intents on an NIC project to ALLOW or BLOCK packets of the traffic according to the specified flow conditions.

Getting ready

Have your Mininet topology configured and the last NIC version compiled on your machine.

How to do it...

Perform the following steps:

1. Start your Mininet topology with a minimum of three hosts. For this example, we will create a topology with three switches and three hosts and create an ALLOW rule using the VTN renderer and then, update these intents to BLOCK all traffic between both.
2. Execute the Mininet topology:

--[cut]--
$ mininet@admin:~$ sudo mn -controller=remote ,ip=<controller_ip> --topo tree,2
--[cut]--

3. Start karaf:

--[cut]--
./karaf clean
--[cut]--

4. Install the NIC features:

--[cut]--
karaf> feature: install odl-nic-core-mdsal odl-nic-renderer-vtn
--[cut]--

5. Create the intents using the REST API:

--[cut]--
./provision_h1_and_h2.sh <your_controller_ip>
./provision_h2_and_h3.sh <your_controller_Ip...
