SDN Migration Tutorial Part 3 – Final Conversion

In our earlier posts “SDN Migration Tutorial Part 1” and “SDN Migration Tutorial Part 2“, we talked about the initial setup of the OpenDaylight Summit tutorial network and changed the first Pica8 switch (L3SW 1) from L2/L3 to OpenFlow.

In this post I will go over the final step, converting the second switch to OpenFlow and showing a fully functional SDN enabled network.

First, our final design:

ODL_Network_Second_ODL

As you can see, we have now connected L3SW 4 to the ODL controller and put a physical connection back to the server running Quagga.

Again, since we are using PicOS here (this may change before the demo), we enable crossflow mode for simplicity.

Next we enable the interfaces in crossflow mode

We then create the switch under OVS

Then we need to add the new interfaces to Quagga and remove the unnecessary ones.

Then update the Quagga BGP configuration to add the new host network (10.4.4.1) and remove the old L3SW 4 peer.

Once this is all done, you can view the devices on OpenDaylight
