WAN Dynamics is thrilled to announce a strategic partnership with Netskope, a global leader in Secure Services Edge (SSE) & Software Defined Wide Area Networking (SD-WAN). This collaboration aims to harness our combined expertise in SD-WAN, SASE, SSE, and ZTNA technologies, establishing the blueprint for the next-generation Wide Area Network.

The ever-evolving world of technology has seen some remarkable developments over the past few years, particularly in the realm of networking. One company at the forefront of these innovations is WAN Dynamics, a company that has been transforming the way businesses manage their network infrastructure in offices, datacenters and the cloud.

WAN Dynamics received a message from a customer late one evening that no network services company wants to get: “We performed a code upgrade and broke connectivity to our disaster recovery site”. This customer had a datacenter interconnect (DCI) with BGP routing and VXLAN between the datacenters but after the EOS upgrade there was reachability issues between them. I jumped in to assist and at first glance, things looked good. The switch interfaces and BGP sessions were up and there was full connectivity from VTEP to VTEP in the datacenter interconnect. That said, MAC addresses were not being learned across VXLAN. Hmmm, wonder why that would be? I decided to check the switch logs for any potential clues as to what could be happening. Aha! in the log buffer there are messages about VXLAN being disabled:

As utilization of the public cloud grows and solutions like SD-WAN and VoIP overtake legacy communications products, good connectivity has grown more important than ever. More and more network engineers are opting for higher bandwidth connections and instituting more stringent standards on redundancy to support these needs.
