EVPN Technical Deep Dive

Overall rating: 4.70 Instructor: 4.70 Materials: 4.72 more …

Ethernet Virtual Private Networks (EVPN) technology has emerged as the unifying control plane used to implement layer-2 and layer-3 VPNs in data center and service provider networks. It’s been implemented by major router and data center switching vendors and is widely used to build scalable overlay virtual networks.

This webinar will help you grasp the EVPN fundamentals, potential use cases, and its benefits and drawbacks. The deep dive part of the webinar discusses the technical details that will enable you to deploy and troubleshoot EVPN in multi-vendor environments. The advanced parts of the webinar also cover MLAG integration, EVPN multihoming and service insertion.

Service Insertion in EVPN Networks

Layer4-7 Services insertion is an eminent requirement within Data Center. With the evolution of Fabric deployments, the environment change from previous centralized functions to more distributed ones.

The VXLAN BGP EVPN fabric does support the well-known use-cases of Firewall and Load Balancer insertion, more commonly referred to as Layer-4 to Layer-7 Network Services, and we'll cover the concepts around Tenant Edge, Intra Tenant and the combination of both.

Further, we will discuss how to attach network services devices in a single-homed or multi-homed VTEP scenario. Last but not least, we will look at how we could integrate load balancers and what options exist in creating a “simple” Service Chain. There will also be goodies for fans of selective traffic redirection and friends of Virtual Network Functions.

Running EVPN and VXLAN on Hosts

The advent of network disaggregation has brought forth the availability of sophisticated and robust open-source routing suites running on Linux or OpenBSD. This opens up many possibilities, including running a routing suite on an end host, resulting in a standards-based solution devoid of any vendor lock-in. Not surprisingly, some operators have already started doing this to support their OpenStack or Kubernetes deployments.

In this part of the EVPN webinar Dinesh Dutt explains what it means to run EVPN on hosts, what are the benefits, and how it works... including a working demo of the concept.

About the webinar

perfect. unfortunately i missed the beginning part but will review recordings. thanks a lot!

Boris Khasanov
I thought the presentation was excellent, and Dinesh did a really good job of explaining the technology. I do think some more diagrams would have been helpful in Dinesh's presentation though. The one slide he had up that did have a diagram made things easier to ingest where I found my mind working quite a bit harder, and not catching everything, in absence of a good visual.
Steven Simonds
I'm assuming the plan is to continue where we left off with Dinesh on the next April session? I'm really interested in what was coming next in the slide deck. I work at a company that deployed BGP EVPN with Cisco 9Ks, so all of this content is very relevant and interesting. I can't wait to hear more!
William Parsley
I enjoyed the session. Dinesh's sound quality was pretty terrible, but I suspect it will be resolved on the recorded video since he was recording locally.
Andrey Khomyakov
while learning it is great to see the packet walk, we skipped past what BGP EVPN NLRI looks like for different Route Type 2,3,5

we didn't touch RT 1,4
Mark Horsfield
Presenter was clear, precise and concise.
Host always on top.
Great to see I followed the right direction for my company
Antonio Boj
Everything was just great
Boris Khasanov
Good session but pretty fringe topic. Something to put in my nack pocket for the future so glad I attended.
