Azure virtual networks (VNets) connected with a VNet-to-VNet connection can communicate through a secure IPSec/IKE encrypted tunnel using Azure's backbone network without ever traversing the public internet. VNet-to-VNet connections can connect VNets in different regions, Azure subscription, and associated with different Azure Active Directory tenants. VNet-to-VNet connections are ideal for setting up your own geo-replication or synchronization with secure connectivity over Azure's backbone network and for connecting VNets in multi-tier applications with isolation or administrative requirements between tiers.

In this lab, you will establish a VNet-to-VNet connection to allow a virtual machine to access another the virtual machine in a different VNet.

Lab Objectives

Upon completion of this lab you will be able to:

• Understand VNet-to-VNet connections and when you would prefer them over other methods for connecting VNets
• Create VPN gateways using the Azure Portal and Azure CLI
• Configure VNet-to-VNet connections between VPN gateways
• Test VNet-to-VNet connection connectivity

Lab Prerequisites

You should be familiar with:

• Basic understanding of Azure networking concepts including VNets, subnets, and network security groups
• Working with at the command-line in Linux and prior experience with the Azure CLI is beneficial

You can fulfill the prerequisites by completing the Introduction to Azure Virtual Networking Course and the Linux Command Line Byte Session Learning Path.
