Latest addition to network testing and simulation: Containerlab

Until recently all existing virtual lab solutions were based on vendor appliances provided as virtual machines. Such an approach allowed us to emulate closely the real HW (some of those appliances had virtualized data planes as well - e.g. vEX, vMX). However this is not always the desired case.

Virtual Labs: running network topology on a plain laptop

For a very long time whenever someone wanted to create a network playground, they had to use physical equipment. Although such an approach had some pros, they were quickly outweighed by the cons, such as: price of equipment, manual cabling required to set up the environment, noise, power consumption - the list is long.

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.
