Data Center Interconnects

Are you designing a network with multiple data centers? Are you familiar with the modern Data Center Interconnect (DCI) technologies? Can you decide when to implement layer-2 DCI ... or defend your decision to stick with routing between data centers? Do you know which Service Provider offerings will introduce the least complexity in your design? What technology should you use if you can only get IP connectivity between your locations?

You’ll get the answers to all of these questions in the Data Center Interconnects webinar.

This webinar (completely redesigned in early 2019) describes three types of data center interconnects, including the benefits and drawbacks of each type:

  • Layer-3 interconnects (routed connections between data centers);
  • Layer-3 interconnects with path separation (multiple isolated routed connections)
  • Layer-2 interconnects (VLANs stretched across multiple data centers with inter-data center bridging).


After this webinar, you’ll understand the benefits and drawbacks of different data center interconnect designs and have an overview of major DCI technologies including:

  • Local and global (DNS) load balancing;
  • Path separation provided by multi-VRF or MPLS/VPN;
  • Locator/Identity Separation Protocol (LISP);
  • Multi-chassis LAG with DWDM or pseudowires;
  • TRILL/SPB with DWDM or pseudowires;
  • MPLS transport over GRE tunnels;
  • Overlay Transport Virtualization (OTV);
  • EVPN using either VXLAN or MPLS transport.


The webinar does not address platform-specific issues, device configurations or performance guidelines. You can learn more about those topics in numerous Cisco Press books and courses offered by traditional training companies.

Target Audience

If you are designing or deploying redundant data centers or data center interconnects, you have to attend this webinar.

To attend this webinar, you should be familiar with modern data center technologies and have a good understanding of IP routing and IP routing protocols (we'd recommend CCNP-level knowledge). Familiarity with MPLS and MPLS/VPN will help you better understand the MPLS/VPN scenarios.

If you’re not familiar with emerging data center technologies, including server virtualization and long-distance virtual machine mobility (for example, vMotion), I would strongly recommend that you watch the Data Center 3.0 for Networking Engineer webinar first.

Feedback from the attendees

The presentation was first-class. I thought it was exceptional value for money and covered the topic in an interesting and thought-provoking way. As always, Ivan demonstrated why he is at the absolute top of his field. His clear explanations and detailed knowledge of the subject matter raised my knowledge of the topic to another level.

About the webinar

This is a great non-vendor centric overview of DCI technologies and respective pro's and con's. I like the fact that it's to the point and Ivan's real world experience is the value add. As a network design engineer my job is no longer about what cli commands to execute but about making the right network technology choices for specific business cases. This is where Ivan's training webinars shine through, I have to yet see similar vendor presentations (most of them just boast the features and capabilities of their new products)

Perfect for planning and discussing data center fail-over AOAs with customers.
Andrew S Stanley
Very informative and topical considering the prevailing trends of data centre consolidation and virtualization
Ketan Sawant
Great webinar! Especially for people not very experienced in the subject.
Ad Spelt
Ivan treats a very contentious subject in a well-balanced manner. The analysis of failure scenarios is particularly recommended.
Leendert van den Dool
This webinar is an excellent overview regarding current DCI design challenges. I would highly recommend to watch it for anyone working in the networking and datacenter space. Sober networkers should watch it thoughtfully at least two times. L2 DCI fans should watch it once in a month, until reaching a solid grasp.

The @ioshints DCI Interconnect webinar has a section on LISP. goodly.
I just attended @ioshints DC Interconnect webinar - really excellent, incredibly detailed and great value.
