POX Openflow Controller Installation: POX is a lightweight OpenFlow controller that is written completely in Python that is targeted for developers to spin up their own controllers. The nice thing about POX is if you want an OF controller spun up in as fast as you can type git clone etc, you got it. It supports the same tools that NOX …
We continue to destroy our nice clean data centers to facilitate poor application architectures that do not scale in a layer 3 fashion. We continue to come up with new technologies using old architectures to turn our networks into flat data centers under the guise of “cloud mobility”. Ok sorry, I got that out of my system. Open vSwitch is …
Quick install how to for Installing and Configuring OpenvSwitch on Ubuntu 12.04 (Precise Pangolin) with the nightly OVS build. Before I start, I must point out the great progress the dev team has done in such a short time. All of the old gotchas in earlier releases on implementation are long gone. I am going to revisit the KVM integration …
This is a quick tutorial for basic MPLS/VPN with Cisco IOS configuration. The tutorial exemplifies basic PE to P to PE configuration on three Cisco 7200s running in GNS3 with IOS. R2 is configured as a route reflector P node and R4, R6 and R3 are PE node route reflector clients. The IGP is OSPF with R2 as the ABR. Loopback1 …
Quick notes on OTV. I have not put this on lab gear yet so there may be typos. It does require licensing so make sure you have that budgeted, if not its a 20kish surprise which sucks.

Here is a quick post for setting up GRE tunnels on OpenVswitch. Both Vswitch boxes are attached to an OpenFlow Beacon controller. More up to date how-to can be found here: Configuring VXLan and GRE tunnels on OpenvSwitch KVM live storage migration makes an interesting story and run at VMware tools. The dreaded layer2 data center link conversation may never …
This tutorial is for installing Open vSwitch with KVM in order to replace traditional hypervisor Ethernet switching using Linux bridging with Open vSwitch. I rebuilt this box becuase as fun as it was to setup OpenStack (I think) there are a million modules that would take more time to clip out rather than just rebuilding. Anyone gotten Nova integrated into …
My notes from an OpenStack & Ubuntu 11.10. These are only my notes. Lots of errors. It was a fairly painless install. I didnt have the lab gear setup with two Nics so I got a bit kludgy at the end. I think the interesting component will be to replace the Openstack bridging with OpenVswitch. sudo apt-get install rabbitmq-server sudo …
