Azure ExpressRoute Tutorial

Introduction to Azure ExpressRoute

Azure ExpressRoute is a service that provides a private connection between an on-premise infrastructure and Microsoft Azure data centers. Unlike typical internet connections, ExpressRoute offers more reliability, faster speeds, consistent latencies, and higher security.

Benefits of Using Azure ExpressRoute

By using Azure ExpressRoute, you can achieve the following benefits:

  • Enhanced security by avoiding the internet.
  • Increased reliability with a private connection.
  • Consistent network performance and low latency.
  • Ability to scale bandwidth as needed.

Setting Up Azure ExpressRoute

To set up Azure ExpressRoute, follow these steps:

  1. Log in to the Azure portal.
  2. Navigate to "Create a resource" and search for "ExpressRoute".
  3. Click on "Create" and fill in the necessary details such as Resource Group, Region, and Circuit Name.
  4. Choose your provider and complete the required fields.
  5. Review and create the ExpressRoute circuit.

Example: Creating an ExpressRoute Circuit

Here is an example of creating an ExpressRoute circuit using Azure CLI:

az network express-route create --name MyExpressRoute --resource-group MyResourceGroup --location eastus --bandwidth 200 --peering-location SiliconValley --provider "Equinix"
{ "name": "MyExpressRoute", "resourceGroup": "MyResourceGroup", "location": "eastus", "bandwidth": 200, "peeringLocation": "SiliconValley", "provider": "Equinix", ... }

Managing ExpressRoute Circuits

Once your ExpressRoute circuit is created, you can manage it using the Azure portal or Azure CLI. For example, to view details of an existing circuit, you can use the following command:

az network express-route show --name MyExpressRoute --resource-group MyResourceGroup
{ "name": "MyExpressRoute", "resourceGroup": "MyResourceGroup", "location": "eastus", "bandwidth": 200, "peeringLocation": "SiliconValley", ... }

ExpressRoute Peering

ExpressRoute supports multiple peering options:

  • Azure Private Peering: Used for direct connectivity to Azure virtual networks.
  • Azure Public Peering: Used for accessing Azure services that are accessible via public IP addresses.
  • Microsoft Peering: Used for accessing Microsoft online services, such as Office 365 and Dynamics 365.

Troubleshooting ExpressRoute

Here are some common troubleshooting steps if you encounter issues with ExpressRoute:

  • Verify the physical connectivity with your service provider.
  • Ensure the configuration settings match between Azure and your on-premises network.
  • Check for any service interruptions or maintenance updates from Azure or your service provider.

Conclusion

Azure ExpressRoute provides a robust, reliable, and secure connection between your on-premise infrastructure and Azure. By following this tutorial, you should be able to set up and manage your ExpressRoute circuits effectively. Remember to monitor and manage your circuits regularly to ensure optimal performance.
