Overview of this book

Frustrated that your company’s network changes are still a manual set of activities that slow developers down? It doesn’t need to be that way any longer, as this book will help your company and network teams embrace DevOps and continuous delivery approaches, enabling them to automate all network functions.

The Nuage VSP multicast support

The Nuage VSP Platform has the ability to route multicast between the following Nuage VSD entities:

  • Layer 2 and 3 domains

  • Zones

  • Subnets

  • VPorts attached to VMs

Multicast can be routed into the overlay network, which is a unique feature of the Nuage VSP platform. Multicast traffic is routed into the overlay network in Nuage by configuring dedicated VLANs on the underlay layer 2 network, which are attached to compute nodes. This allows the compute (hypervisors) on the underlay network to use the dedicated VLANs, which are ip'd on a per rack basis, to transmit and receive multicast traffic.

To route multicast traffic across the underlay, the Nuage VRS will duplicate the multicast packets and leak it into the overlay network in a controlled fashion. This is so the overlay network is not flooded with unnecessary multicast traffic, which can cause performance implications to the overlay network if it was not controlled. This makes the Nuage multicast setup highly scalable...
