EVPN’s 4 critical benefits for digital transformation



Digital transformation demands more of everything: speed, throughput, agility and scalability. That’s why organizations are rethinking traditional layer 2 switched data center architectures and moving towards intelligent layer 3 routed network designs. With a layer 3 architecture, your data center can use proven routing protocols to simplify troubleshooting, facilitate upgrades, scale efficiently and converge traffic.

But what about the applications, storage appliances and multi-tenant environments that still require traditional layer 2 connectivity? Legacy protocols that enable layer 2 traffic to run over a layer 3 routed infrastructure have significant limitations that become serious obstacles when the data center must scale, accommodate multiple vendors’ systems or support multi-tenancy. Fortunately, there’s a scalable, simple, non-proprietary solution. Enter EVPN.

Cumulus’ unique Virtual eXtensible Local Area Network (VXLAN) Ethernet Virtual Private Network (EVPN) solution offers unmatched interoperability and efficiency. By adding VXLAN distributed routing, Cumulus EVPN undoes all of the complications of layer 2 connectivity and frees you from reliance on proprietary controllers. Looking for proof that EVPN delivers on that promise? We’ve got plenty of evidence, so here’s four major advantages of utilizing EVPN to meet the demands of digital transformation.

1) Accommodate growth without disruption

With Cumulus EVPN, you can quickly and easily support new applications, storage systems, multi-tenancy requirements and business growth using the same infrastructure. Intelligence resides in the control plane, not in hundreds of lines of manual configuration, so new VXLAN tunnels and switches can be added without disruption.

2) Preserve multivendor investments

At Cumulus Networks, we believe in giving customers choices and putting the power in their hands so they can build the most customizable network that meets their needs. Cumulus EVPN ensures interoperability between multiple vendors’ systems by supporting both symmetric and asymmetric VXLAN routing modes, as long as they adhere to VXLAN and EVPN standards. Customize your network with your choice of vendors, change your data center footprint at any time, save staff time and reduce the risk of error.

3) Avoid CAPEX and reduce OPEX

You don’t need to add costly, proprietary controllers — Cumulus EVPN automatically discovers VXLAN tunnels and exchanges information among VXLAN nodes. Just a few lines of code give you a single configuration for all devices and routes. Your budget will appreciate you not spending extra cash on controllers, and your network engineers will love how this simple solution helps them spend less time on complicated, manual configurations.

4) Increase overall efficiency

Cumulus EVPN enables you to free up bandwidth while delivering traffic more efficiently, accomplishing way more work in far less time. You can support active-active data centers with redundancy and high availability, and you can easily isolate tenant traffic in a multitenant environment.

Any—or all—of these improvements increase scalability, performance and efficiency, which translates to operational savings.
