In many cases, the short answer is probably not. In this post, we will review some options to ensure high availability of GlobalProtect services now that it’s become a mission critical application for many organizations.

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:

Connecting remote users into corporate IT resources has never been trivial. With the shift to work from remote already well underway for many before 2020, the global COVID-19 pandemic catalyzed the transition dramatically. The change happened so fast, many organizations struggled to get their remote users connected when working from home as it became a requirement. Remote access to an organization’s applications traditionally necessitates creation of a virtual private network (VPN) connection of some kind for these users to safely encrypt and secure access to sensitive data they need to do their jobs.

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.

Six years ago, in 2014, I worked at a regional telecommunications service provider that had encountered this technology called “SD-WAN” in our market. I was the head of solutions engineering at the time and it was the first that I had heard of such a thing!

Recently while setting up a new Fortinet FortiGate firewall High Availability (HA) pair, I ran into an issue that I hadn’t encountered before. The goal was to set up an active/standby HA pair and having done this many times, didn’t think much of it when configuring the normal HA settings...

Even though managing Arista switches is pretty great, sometimes performing things like software upgrades can be tedious and boring, especially when there are a lot of switches to upgrade at a time. Here at WAN Dynamics, we like to solve tedious problems with automation so to for this particular challenge.

What a great week at VMware's VMworld 2018 event in Las Vegas, the first VMworld conference for WAN Dynamics. Our primary interest at the show was to learn more about what is in store for the VeloCloud product as it is one of the key solutions for our managed SD-WAN product, DynaWAN. After this event, it's more clear than ever that VMware might just be the best organization for VeloCloud to have been acquired by.
