EVPN Technical Deep Dive

Overall rating: 4.71 Instructor: 4.71 Materials: 4.75 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.

  • Using MLAG in EVPN/VXLAN environments
  • Cisco vPC Fabric Peering details

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.

MPLS-Based EVPN in Service Provider Networks

Krzysztof Szarkowicz will explain how EVPN works with MPLS transport and how service providers use EVPN with MPLS to build next-generation L2VPN and L3VPN networks.

Multi-Vendor EVPN Deployments

A cursory look at the recommended solution by any of the popular data center switching vendors leads you to think that there's no common way to do EVPN across all the vendors. This section evaluates different EVPN implementations by the most popular vendors in the data center space, starting with vendor configs, show commands and their outputs etc.

Knowledge of these details is useful as you navigate the EVPN waters across different networks over the course of your career, and for a deeper understanding of EVPN. We'll use this lens to also examine the model that works best across all vendors, and so is a safe bet to deploy when you're in doubt.

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.
Covering not only technical details but use cases and assets connected to EVPN networks. Very good webinar - thanks.

Slawomir Janukowicz
Will be great to have Deep Dive EVPN session, as a lot of topics were left behind the scene.
Andrei Cebotareanu
Thank you for the professionalism and expertise.
James Hamilton
Learn from the Industry veterans as nothing compares to the experience shared by the Maestros.
shuja naqvi
This is a wealth of information from one of the leading sources of knowledge on EVPN/VXLAN. Well worth the time, and was a great way for me to shore up the parts of EVPN/VXLAN that I was unsure of.
Chris Cummings
Outstanding instructors. Both of them areo different but both of the excellent.
