Video: MLAG with EVPN Deep Dive

In November 2022 I described some of the intricacies of using EVPN to implement MLAG control plane. You might have noticed that I didn’t dive deep into EVPN details, and I had a good reason for that – Lukas Krattiger did a wonderful job describing how MLAG works with EVPN in the EVPN Deep Dive webinar.

Video: EVPN Multihoming Deep Dive

After starting the EVPN multihoming versus MLAG presentation (part of EVPN Deep Dive webinar) with the taxonomy of EVPN-based multihoming, Lukas Krattiger did a deep dive into its intricacies including:

  • EVPN route types needed to support multihoming
  • A typical sequence of EVPN updates during multihoming setup
  • MAC multipathing, MAC aliasing, split horizon and mass withdrawals
  • Designated forwarder election

Could I Use netlab instead of GNS3?

I’m often getting questions along the lines of “I’m using GNS3. Could I replace it with netlab?"

TL&DR: No.

You need a set of functions to build a network lab:

  • Virtualization environment (netlab supports VirtualBox, libvirt, Docker, Podman)
  • An orchestration tool/system that will deploy network device images in such an environment (netlab supports Vagrant and containerlab)
  • A tool that will build orchestration system configuration (netlab core functionality)

Video: EVPN Multihoming Taxonomy and Overview

I promised you a blog post explaining the intricacies of implementing MLAG with EVPN, but (as is often the case) it’s taking longer than expected. In the meantime, enjoy the EVPN Multihoming Taxonomy and Overview video from Lukas Krattiger’s EVPN Multihoming versus MLAG presentation (part of EVPN Deep Dive webinar).

Video: Bridging Beyond Spanning Tree

In this week’s update of the Data Center Infrastructure for Networking Engineers webinar we talked about VLANs, VRFs, and modern data center fabrics.

Those videos are available with Standard or Expert ipSpace.net Subscription; if you’re still sitting on the fence, you might want to watch the how networks really work version of the same topic that’s available with Free Subscription – it describes the principles-of-operation of bridging fabrics that don’t use STP (TRILL, SPBM, VXLAN, EVPN)

Video: Kubernetes Services Types

Kubernetes services are like networking standards: there are so many to choose from. In his brief introduction to Kubernetes service types, Stuart Charlton listed six of them, and I’m positive there are more. That’s what you get when you’re trying to reinvent every network load balancing method known to mankind ;)

Parts of Kubernetes Networking Deep Dive webinar (including this video) are available with Free ipSpace.net Subscription.
