## AI overview

This article explains how physical network links are represented in virtual labs. It examines virtual bridge switches, Linux bridges, Vagrant and libvirt networks, tap interfaces, and the veth-pair method for connecting containers to Linux bridges.

## Source excerpt

There are three major ways to connect network devices in the physical world: Point-to-point links between devices (usually using some variant of Ethernet) Multi-access layer-1 networks running some IEEE 802.x encapsulation on top of that (GPON, WiFi, Ethernet hubs) Multi-access switched layer-2 network (dumb switches, hopefully running some STP variant) Implementing these connections in virtual labs is a bit harder than one might think, as all virtualization solutions assume you plan to run virtual servers connected to Ethernet segments.
