Presented by Joe Lentz, Systems Engineer • Arista Networks
In this presentation, we will explore the different network segmentation models available, including VLANs, VRFs, and group-based segmentation models.
We will begin with an overview of the different segmentation models and discuss their benefits and drawbacks. VLANs provide a simple way to segment traffic but do not scale well in larger environments. VRFs offer more robust isolation but can be complex to manage. Group-based segmentation models offer a flexible and scalable way to segment traffic based on the endpoint itself rather than the network. We will discuss the implementation and configuration of each of these models and provide examples of how they can be used in different scenarios.
Next, we will discuss how EVPN with either VXLAN or MPLS transport can be used as an attachment point to allow for segmentation to cross the network device boundary and become a network-wide policy.
Finally, we will compare the different models to help you choose the best segmentation approach for your network, as well as how to layer these together to have a more complete design. By the end of this presentation, you will have a better understanding of modern segmentation architectures and be equipped to make informed decisions for your network.
