 ## What is UDR management?
 
 Azure Virtual Network Manager allows you to describe your desired routing behavior and orchestrate user-defined routes (UDRs) to create and maintain the desired routing behavior. User-defined routes address the need for automation and simplification in managing routing behaviors. Currently, you’d manually create User-Defined Routes (UDRs) or utilize custom scripts. However, these methods are prone to errors and overly complicated. You can utilize the Azure-managed hub in Virtual WAN. This option has certain limitations (such as the inability to customize the hub or lack of IPV6 support) not be relevant to your organization. With UDR management in your virtual network manager, you have a centralized hub for managing and maintaining routing behaviors.

 In Azure Virtual Network Manager UDR management, users can now create up to 1,000 user-defined routes (UDRs) in a single route table, compared to the traditional 400-route limit. This higher limit enables more complex routing configurations, such as directing traffic from on-premises data centers through a firewall to each spoke virtual network in a hub-and-spoke topology. This expanded capacity is especially useful for managing traffic inspection and security across large-scale network architectures with numerous spokes.
 
+For example, in a hub and spoke topology, it is common for users to require network traffic to be inspected or filtered by a firewall in the hub virtual network before reaching the spoke virtual networks. The Azure Virtual Network Manager supports up to 1000 spoke virtual networks and allows the configuration of the firewall subnet's route table to support up to 1000 User-Defined Routes for traffic from the firewall to the spoke virtual networks. To achieve this, follow these steps:
+1. Create an Azure Virtual Network Manager instance.
+1. Create a network group and include the subnet containing the firewall in this group.
+1. Establish a routing configuration and create a rule collection, setting the target network group as the one created in Step 2.
+1. Define a routing rule by adding the address spaces of the spoke virtual networks. Set the next hop to "virtual appliance" and specify the firewall's IP address as the next hop address.
+1. Deploy this routing configuration in the region where the firewall subnet is located.
+
+This method allows the firewall subnet's route table to accommodate up to 1000 UDRs. When adding a new spoke virtual network, simply include its address spaces in the existing rule and redeploy the routing configuration.

 - Azure Virtual Network Manager requires a managed resource group to store the route table. If an Azure Policy enforces specific tags or properties on resource groups, those policies must be disabled or adjusted for the managed resource group to prevent deployment issues. Furthermore, if you need to delete this managed resource group, ensure that deletion occurs before initiating any new deployments for resources within the same subscription.
 - UDR management allows users to create up to 1000 UDRs per route table.

 In this article, you learn how to deploy multiple hub-and-spoke topologies, and manage user-defined routes (UDRs) with Azure Virtual Network Manager. This scenario is useful when you have a hub and spoke architecture in multiple Azure regions. In the past, customers with firewalls or network virtual appliances performed many manual operations to do cross-hub and spoke in the past. Users needed many user-defined routes(UDRs) to be set up by hand, and when there were changes in spoke virtual networks, such as adding new spoke virtual networks and subnets, they also needed to change user-defined routes and route tables. UDR management with Virtual Network Manager can help you automate these tasks.
