Configuring VXLAN and GRE Tunnels on OpenvSwitch
I have done a couple of GRE tunnel how-tos using OpenvSwitch (OVS). I had been itching to give VXLan a spin in OVS so why not ferret out someones tree on GitHub.

OpenvSwitch Configure from Packages and Attaching to a Floodlight OpenFlow Controller
OpenvSwitch Configure from Packages and Attaching to a Floodlight OpenFlow Controller: Couple folks have asked about installing OpenvSwitch from packages on Ubuntu 12.04 as opposed to from source. The default repos have v1.4 up so almost at the latest v1.4.1. OVS will be the de facto vSwitch in the hyper-scale providers in the future in my opinion. As Vmware’s Nicira acquisition …

Posting a Juniper VPLS how-to on a couple of J-series routers. Have been pretty SDN focused lately so wanted to get some real stuff in for a post. Docs on JunOS VPLS can be shaky so nothing like a couple real configs to plugin your address in the lab if having problems with L2 VPNs. This includes MPLS VPLS configuration …
