Introduction Within this 3 part series on how to build a virtual Nuage SDN lab, we previously looked at the topology, the OpenStack installation and VSD deployment. Next, we will now look at the steps involved in installing the VSC (Virtualized Services Controller). Once installed our controller will talk XMPP

Introduction Welcome to this 3 part course on installing a virtualized Nuage VCS (DC-SDN) lab. The series will be broken down into the following parts: * Part1: VSD Installation (Management Plane) * Part2: VSC Installation (Control Plane) * Part3: VRS Installation (DataPlane) Note: The VSP version we will be installing will be 5.

What is a BGP Peer Group? BGP peer groups are used to simplify configuration and to improve performance. This is achieved by assigning the same outbound policy to each of the neighbours. Because UPDATEs are generated only once per peer group rather multiple times for each neighbouring router, peer groups
