Installing Open vSwitch with KVM
This tutorial is for installing Open vSwitch with KVM in order to replace traditional hypervisor Ethernet switching using Linux bridging with Open vSwitch.

MVPN Multicast with Multi-Protocol BGP MPLS VPN on Cisco IOS
Below assumes you have the basic MPLS transport setup. MVPN or multicast vpn is deployed on Cisco gear using Multicast Distribution Trees (MDT). This information is encapsulated in the MPBGP MPLS sessions to be distributed into label switch paths (LSPs) for forwarding. The following code will produce a basic functioning Cisco IOS MDT multicast environment. A tutorial for that can …
