OPENVSWICH – Campus Model with Layer2 Access built with Open-Source Applications

In the first tutorial we showed how to create Openvswitch extension and submit it to Tinycore repository. There were also presented after-install steps for Openvswitch adapted for specific Core needs. In a previous tutorial we performed several tests in order to test configuration such as vlans, 8021q trunks and VLAN interfaces widely used in typical multilayer switches. In this tutorial […]

OPENVSWICH - Creating and Submitting Openvswitch Extension To Tinycore Repository

In May 2011, I read a request for installation Openvswitch on Qemu image. I started to play with Openvswitch and finally became fan of this project. I soon realized how powerful can be Openvswitch, offering many features so far available only in hardware switches. After several days spent with playing with Core Linux and Openvswitch I was […]

OPENVSWICH - VLANs, Trunks, L3 VLAN interface, InterVLAN Routing - Configuration And Testing

In a previous tutorial we showed how to install Openvswitch on Qemu image with Microcore Linux. At the end of tutorial we created Openvswitch extension and submitted it to Microcore public repository. Assuming that Openvswitch is configured and functional, we are ready to make three labs which  helps us to test features such as VLANs, trunks […]
