Azure Networking, User Defined Routes, and Network Virtual Appliances

This video was intended to show User Defined Routes (UDRs) and a few items were added on to demonstrate how they work.  It starts with some Azure Networking Basics and then we review a hub and spoke network.  From there, A Windows Server with Routing and Remote Access Services (RRAS) is configured as a Network Virtual Appliance (NVA) to route traffic between the spokes in the network.  UDRs are configured on the spoke subnets that send inter-spoke traffic to the NVA.  After that, we add a firewall into the network and direct internet traffic to the firewall with a default route in the UDR.

Azure Hub and Spoke Virtual Network (VNet) with a VPN Gateway

In this video, we create a hub and spoke network in Azure by peering our spoke VNet’s to a centralized, Hub Virtual Network.  Then we use a VPN Virtual Network Gateway to enable gateway transit connectivity between the spokes.  Next, we configure routing with Azure Route Tables and User Defined Routes (UDR) to send traffic going to other spokes to the hub.  Then we log into a virtual machine and verify connectivity.
