Ethernet VPN explained: benefits, use cases, and key concepts

The requirement of Layer 2 connectivity has driven Ethernet-based fabrics and Layer 2 virtual private networks (VPN) to be adopted by internet service providers, cloud operators, and enterprises in their converged networks. A new set of requirements, not initially considered in the design of existing technologies and protocols, has led to the deployment of solutions with certain shortcomings.

Getting started with vManage client: essential features and functions

Working with REST API on cutting-edge systems can be challenging at times. Rapid evolution and new features often lead to changes in the structure of REST API calls. These can be just cosmetic but still require an effort to adjust existing scripts. This problem can be easily handled by the SDKs dedicated to systems such as Cisco Meraki or Cisco DNA Center.

IPsec vs. OpenVPN — what are the differences?

Quick answer: IPsec is a suite of secure network protocols that are based on open IETF standards and OpenVPN is an open-source protocol that is used by an application with the same name. In other words, IPSec is a framework but OpenVPN is an end-user solution. It doesn’t follow that OpenVPN is worse than IPsec. If OpenVPN as a solution fulfills your requirements it could be the best choice for you. The strength of IPsec lies in three words: open IETF standards. By meeting these standards, two different implementations from different vendors can successfully operate together in the most secure way without having a single common line of code.
