What is Nuage? Nuage is an SDN platform, that provides a number of products, such as DC-SDN and SD-WAN. Also known as: * VCS - Virtualized Cloud Services - DC-SDN * VNS - Virtualized Network Services - SD-WAN Within this article we will look at a feature within VCS, known as Backhaul

Below is a collection of commands, useful in the administration and troubleshooting of the Nuage Networks platform. Further information on the various Nuage components can be found at: GHOST_URL/a-1000ft-view-of-nuage-networks-vsp/ Note: The following commands are based upon 5.0.2R2. VSC Commands Command Description show router route-table Disaply base

Introduction The controller cluster in the NSX platform is the control plane component responsible for managing the hypervisor switching and routing modules. This includes the logical switches and VXLAN overlay. Due to the centralized, decoupled model of the controller, it provides the ability to reduce broadcast traffic, in turn negating

Overlay networks decouple the network services from the underlying physical network infrastructure. This is achieved by running a virtual network onto of the underlay via the use of network encapsulation. There are 2 main types of overlay solutions - Network-Centric and Host-Centric Overlays. Network-Centric With Network-Centric overlays, the network device

Introduction In the world of virtualization and connectivity, the virtual switch is one of the most fundamental components, providing networking connectivity between virtual machines, along with connecting them to the physical world. VMware provides 3 types of virtual switch, the virtual Standard Switch (vSS), the virtual Distributed Switch (vDS), and

When BUM (Broadcast, Unknown unicast and Multicast) traffic is sent out from a VM, the source VTEP must replicate this traffic out to the other VTEPs via VXLAN encapsulation. NSX provides 3 modes of replication - Multicast, Unicast and Hybrid. Multicast Multicast replication utilizes L2 (IGMP) and L3 (PIM) multicast

Within this short article, we will look at the difference between local and directed broadcasts. Local Broadcast A local (link-local) broadcast (255.255.255.255) is performed within the broadcast domain. It is only local and never forwarded. Directed Broadcast A directed broadcast, on the other hand, is the broadcast
